The biggest public backer of World Liberty Financial, the crypto venture co‑founded by the Trump family, has publicly accused the firm of embedding a covert "backdoor blacklisting" feature that allows it to freeze token holdings at will. On Sunday, blockchain entrepreneur Justin Sun posted on X, alleging that World Liberty’s smart contracts for the WLFI token contain a tool that can unilaterally freeze, restrict, or confiscate any user’s assets without cause or recourse. Sun did not provide evidence, but said his own wallet was locked in September, making him the "first and single largest victim" of the alleged mechanism. World Liberty responded on X, stating, "We have the contracts. We have the evidence. We have the truth. See you in court, pal," and directed observers to its own posts for clarification. The company’s official risk disclosures do note that it may block or freeze addresses deemed linked to illegal activity or terms violations – a practice also employed by other crypto issuers such as Tether. Sun, who invested tens of millions of dollars in WLFI and later increased his stake to at least $75 million according to his 2025 posts, has not shared the purported blockchain records that supposedly show his wallet being blacklisted by a single administrative account. World Liberty, launched in 2024, claimed it would empower small investors through a decentralized‑finance app that has yet to launch. Reuters analysis indicated the venture generated **more than $460 million** for the Trump family in the first half of 2025. In March, the U.S. Securities and Exchange Commission settled a 2023 lawsuit against Sun for $10 million, alleging fraud and the sale of unregistered crypto securities. Sun made no admission of wrongdoing. The dispute highlights the murky regulatory environment for crypto in the United States, where the SEC has limited jurisdiction and has declined to comment on the legality of token‑freezing practices.

Arsenal manager Mikel Arteta expressed his pride in his team's performance after they reached the Champions League semi-finals for the first time in their history. The Gunners secured a spot in the last four with a gritty draw against Sporting, despite being without their injured captain Martin Ødegaard and Bukayo Saka.Declan Rice, who was captain in Ødegaard's absence, revealed that he had come off his sickbed to play a crucial role in the match. 'He was shattered,' Arteta said of Rice. 'He had no chance to play today, he wasn’t feeling good at all today, he played 94 minutes at the level that he’s done.'The match was a closely contested affair, with both teams creating chances. Leandro Trossard headed against a post from a Max Dowman corner late on, while Sporting's João Simões fired into the side netting with virtually the last kick of the match.Arteta attributed his team's success to their durability, saying, 'That is the reason why we are the only English team in the competition, because this league and this schedule takes the hell out of you, and it’s very difficult to do what we’ve done.'Rice also addressed criticism of the team's recent performances, saying, 'If you don’t play well, if you don’t play good, take it with a pinch of salt and keep moving.'Arsenal will now face Atlético Madrid in the semi-finals, having maintained their record as the only unbeaten team left in this year’s competition. They will also look to bounce back from their recent Premier League defeat to Bournemouth when they face Manchester City on Sunday.

The Leeds Song Festival, a top-tier celebration of the vocal arts, continues to push the envelope with its innovative performances. Director Joseph Middleton's determination to think outside the box while honoring the festival's roots in traditional recitals is evident in two vastly different concerts.The first, 'Haiku', premiered last year in Minnesota and features eight poems taken from a collection of haiku written by Japanese Americans interned during World War II. Baritone Roderick Williams and pianist Iain Burnside brought these distilled musical morsels to life, exploring themes of exile, detention, and deportation.Williams, a master storyteller, breathed life into the songs with his warm vocal embrace and expressive physicality, bringing pain and pathos, wit and wisdom to a kaleidoscopic array of songs. Burnside was his equal, providing a generous and supportive piano accompaniment.The program included highlights such as Gerald Finzi's setting of Thomas Hardy, 'Waiting Both', and Joan Trimble's 'My Grief on the Sea', a delicate Irish love song. The evening ended with Maria Grever's rumba-inflected 'What a Diff'rence a Day Made', a perfect laid-back note.The second concert, 'Dunwich', a festival commission, stretched the idea of a traditional recital to the limit. This haunting soundscape combined field recordings made at the site of Dunwich's last remaining gravestone with Martin Iddon's shape-shifting writing for piano. The piece featured slyly sinister accounts of local ghost stories, delivered by speaker Gillian Jane Lees, and eerie black-and-white videos by Adam York Gregory.

Manchester United's Harry Maguire will miss his team's upcoming match against Chelsea due to an additional one-match ban imposed by the Football Association. The ban comes as a result of Maguire's reaction to being sent off during a match against Bournemouth last month.The 33-year-old defender was shown a red card at the Vitality Stadium for a foul in the area on Evanilson, which led to Bournemouth sealing a 2-2 draw. Following the incident, Maguire allegedly made a comment towards the officials, stating they were 'a joke.'The FA's written reasons confirmed that the fourth official, Matthew Donohue, submitted an Extraordinary Incident Report Form, claiming Maguire shouted: 'You're a joke. You're all a fucking joke.' Maguire, however, claimed he said 'something along the lines of 'it is a fucking joke.''As a result, Maguire has been imposed a one-match suspension and a £30,000 fine by an independent Regulatory Commission. This suspension adds to the absence of fellow centre-backs Matthijs de Ligt and Lisandro Martínez, potentially leading to young players Ayden Heaven and Leny Yoro lining up at the heart of defence against Chelsea.

Cuba is on the brink of transforming its energy landscape with a bold plan to invest $8bn in renewable energy, which could reduce its reliance on fossil fuels and pave the way for energy independence from the US. The proposal, put forth by the Common Wealth thinktank's Transition Security Project (TSP), suggests that this investment could cover 93.4% of Cuba's electricity generation needs.The US has imposed a crippling energy blockade on Cuba, severely limiting the island nation's access to oil. Since January, Cuba has received only one shipment of oil, from Russia, and its national electric grid has collapsed, leading to repeated blackouts and widespread disruptions.The TSP analysis outlines four different scenarios for Cuba's transition to renewable energy, with costs ranging from $5bn to $19.2bn. The most ambitious proposal would see three-quarters of electricity generation provided by solar power, with wind, hydropower, and bioenergy making up the remainder.The report argues that electricity costs would decrease in every renewable investment scenario, with the cost per unit of energy falling from 14.3¢ per kWh in the baseline scenario to 6.5¢ with $8bn of investment. The transition would require a society-wide transformation, but Cuba has demonstrated its ability to adapt in the past, such as its rapid shift to agroecology and self-sufficiency in the 1990s.The question remains: who would pay for this transition? The report suggests that financing should be understood as "reparative climate finance", with Cubans able to pay back investments through savings on cheaper energy. The transformation would not only benefit Cuba but also set an important example of a rapid energy transition under conditions of external constraint.

In 2020, several nations—including the UK and India—announced ambitious bans on new internal‑combustion‑engine vehicles, while Norway already saw around 60% of new car sales being electric. Australia, however, remained on a different trajectory. Former Prime Minister Scott Morrison dismissed a Labor proposal for a non‑binding 50% electric‑vehicle target by 2030, claiming it would “end the weekend.” The Coalition ignored analyses suggesting that a robust emissions‑cut scheme could deliver a $14 billion net benefit by 2040, and later abandoned plans for an EV‑specific strategy. Five years on, the Albanese government has introduced a vehicle‑efficiency standard mandating annual reductions in average emissions from new cars. Though a long‑awaited move, the policy’s impact will be incremental rather than transformative. March saw a record number of Australians purchasing EVs, yet the market share remains modest—still under 15% of new car sales, up only slightly from 13% in 2025. With fuel prices soaring amid the Iran conflict, the majority of vehicles leaving showrooms are still powered by petrol or diesel, and many will stay on the road for the next 15‑20 years. One bright spot is the surge in second‑hand EV sales, which more than doubled last month despite a tiny baseline. Higher resale values are encouraging broader adoption by making electric cars financially accessible to a larger pool of buyers. Globally, electric vehicles accounted for roughly 25% of new car sales last year. In Australia, the price differential between comparable petrol and electric models averages around 20%, a significant barrier for many consumers. That gap is narrowing, and the potential savings for EV drivers are substantial. Data from energy analyst Simon Holmes à Court—using Amber electricity retailer figures—show that an EV can travel over 40 km per $1 of energy, whereas a conventional car manages less than 5 km per $1 of fuel. Amber’s own smart‑charging platform suggests the distance could reach 160 km per $1 under optimal conditions. Despite such evidence, Australian political discourse often struggles to envision a low‑fossil‑fuel future. Calls for expanded oil exploration, such as Queensland Premier David Crisafulli’s claim of a “sea of oil” in the Taroom trough, lack substantiation and would likely involve costly, long‑term development with uncertain returns. Compounding the issue, the mining sector—Australia’s biggest diesel consumer—receives a 52‑cent‑per‑litre rebate under a national fuel‑tax credit scheme, effectively subsidising over $1 billion annually for diesel use in coal mines. This incentive discourages investment in cleaner truck technologies, even as the safeguard mechanism attempts to curb emissions. Policy recommendations include tightening the vehicle‑efficiency standard to accelerate the shift toward cleaner cars, removing parallel‑import restrictions to boost the supply of affordable second‑hand EVs (as practiced in New Zealand), and reconsidering any road‑user charges on electric vehicles, which currently represent less than 2% of the total fleet. International examples offer guidance: China jump‑started its EV boom by issuing “green” licence plates and imposing hefty fees for fossil‑fuel plates, effectively raising the cost of owning a petrol car by up to $20,000. In sum, Australia’s delayed embrace of electric mobility not only hampers climate goals but also forfeits billions in economic gains. A decisive, well‑targeted policy overhaul could unlock significant consumer savings, reduce emissions, and align the nation with global EV trends.

Great Britain is on the verge of a record‑breaking summer of wind and solar generation, creating the possibility of the first zero‑carbon electricity periods in the nation’s power system.The government’s ambition to achieve a 95% gas‑free grid by 2030 underpins this push, as electrified transport, heat pumps and low‑carbon industry will need a clean power supply to meet climate targets.National Grid ESO (Neso) forecasts that on sunny weekend afternoons the grid could have more renewable power than demand, leaving excess capacity that would otherwise be wasted.To turn surplus into savings, Neso is urging households and businesses to shift flexible loads—such as charging electric vehicles, running dishwashers or doing laundry—to those high‑renewable windows.Leading suppliers Octopus Energy and British Gas have confirmed participation, offering special tariffs that reward consumers for using electricity when it is abundant.British Gas’s “PeakSave” scheme, for example, provides half‑price electricity from 11 am to 4 pm on Sundays, with an even cheaper “Super Sunday” option from 9 am to 5 pm. The company says the tariff has saved over £45 million for more than 1 million customers since its 2023 launch. Octopus Energy reports helping 2 million households save about £11 million, including £3 million in free electricity during periods of high renewable output.Other providers—including Ovo Energy and EDF Energy—offer similar “time‑of‑use” tariffs that charge higher rates when renewables are scarce, giving price‑sensitive users a clear incentive to shift consumption.Beyond bill reductions, flexible demand curtails the need for “constraint payments” to wind and solar farms—payments that reached almost £1.5 billion last year. By encouraging consumers to “turn up” rather than forcing generators to “turn down,” the grid can avoid these costly curtailments.Businesses are also joining the flexibility movement. Tech firms report that adaptable energy use can cut datacenter grid costs by up to 5% and slash emissions by as much as 40%. Danish engineering group Danfoss estimates that if datacentres operated flexibly for just 1% of the time, the pipeline of new facilities expected by 2035 could be accommodated without overloading the grid.In short, leveraging surplus renewable power now—through smart tariffs and demand‑shifting—offers a cheaper, faster alternative to massive storage or grid‑upgrade projects, while delivering tangible savings for consumers and a decisive step toward a low‑carbon British electricity system.

Evan Williams, a 55-year-old horse racing trainer from Wales, has been jailed for three years for attacking a dog walker, Martin Dandridge, 72, with a hockey stick on his land in Llancarfan, south Wales, in December 2024.Williams, who has had significant success in horse racing, including winning the Welsh Grand National with Secret Reprieve in 2020, repeatedly struck Dandridge, causing him serious injuries, including a fractured arm. The incident led to Williams being convicted of causing grievous bodily harm with intent by a unanimous jury at Cardiff Crown Court in March.The judge, Recorder Angharad Price, criticized Williams for taking the law into his own hands, stating, “It is never acceptable to take the law into your own hands. This sentence will be a lesson to you that it is always better to call the police if you think a crime is being committed.” Williams had previously experienced a threatening incident with poachers on his land six weeks before the assault.Williams's barrister, David Elias KC, noted that “If he isn’t there, there is no business,” suggesting that Williams's imprisonment could jeopardize his training business. Williams established Evan Williams Racing in 2003 and has been one of Wales's most successful trainers, achieving top-four finishes in five consecutive Grand Nationals at Aintree between 2009 and 2013.

Arsenal manager Mikel Arteta remains optimistic about his team's chances despite mounting injury concerns, particularly with star player Bukayo Saka sidelined with an achilles issue.Arteta insists he has 'zero fear' that Arsenal could end the season without silverware, but admits there are significant doubts over Saka's return. Saka has not played since the Carabao Cup final defeat to Manchester City last month and Arteta is uncertain when he will be back.'Hopefully it's going to be a matter of days and not weeks,' Arteta said. 'But he has to see when he's loading more, how he responds to that kind of progression.'Arsenal are also facing doubts over Jurrien Timber, Riccardo Calafiori and captain Martin Ødegaard for their Champions League match against Sporting. Additionally, Arteta will make a late call on Declan Rice's fitness after the England midfielder missed training on Tuesday.Despite recent setbacks, including a home defeat to Bournemouth in the Premier League, Arteta remains positive. 'Fire. I'm on fire. I'm on fire,' he said. 'Nothing else. I'm dreaming so much. I've done so much to be in this position because I know how this club was. I just see beauty, opportunity, and I want to get it done for all these people that have been in this journey with us.'
