• Ukrainian has not played since November 2024

• Cas confirms appeal by Mudryk against the FA

The Chelsea forward Mykhailo Mudryk has appealed to the court of arbitration for sport after he received a reported four-year playing ban from the Football Association for the use of a banned substance.

Mudryk has not played a competitive match since November 2024 after he failed a drugs test while on international duty with Ukraine and began a provisional suspension . Under the terms of any four-year ban he would not be eligible for selection again until December 2028, but if an appeal to Cas were successful then the 25-year-old could possibly return next year.

England’s higher education regulator must rebuild trust with troubled sector after series of blunders under previous leadership

In its brief and unhappy life, England’s Office for Students has been offered a series of challenges it has largely failed to meet. This week the latest and most embarrassing of those was unveiled when the high court decisively rejected the higher education watchdog’s attempts to fine the University of Sussex more than £500,000 for regulatory failings relating to Kathleen Stock’s time as an academic at Sussex.

Stock quit Sussex in 2021 , saying she felt ostracised and targeted for her views on gender identity and transgender rights. Here was the highest profile test case that the OfS had seen: a subject of enormous controversy and sensitivity, involving key issues of academic freedom and freedom of speech. But as we now know from Mrs Justice Lieven’s ruling , in its rush to intervene, the OfS managed to tie together its own shoelaces.

The world must accelerate the shift to renewables, regardless of the economic effects of Abu Dhabi’s decision

Opec appears to be the latest casualty of the Iran war. On Tuesday, the United Arab Emirates announced that it was leaving the oil cartel after 60 years. The loss of a critical member is a blow to the group and its de facto leader, Saudi Arabia, in the midst of the biggest supply crisis in history.

This is a geopolitical decision, not merely an economic one. The UAE has built itself into an increasingly interventionist and unilaterally minded power, not only challenging Riyadh’s dominance but undermining its more cautious approach to regional affairs. The rift has become increasingly public and bitter – with Saudi Arabia bombing what it called a UAE-linked arms shipment in Yemen in December. Abu Dhabi, as the main target of Iranian strikes among the Gulf countries, is also enraged by what it sees as a feeble regional response to the current conflict, and has been privately pushing for counterattacks.

Parliament’s failure to change the law on a difficult issue should be the spur to democratic innovation

The prorogation of parliament on Wednesday signals the end of the road for the terminally ill adults (end of life) bill . The proposal to allow some patients in England and Wales, under very specific circumstances, to have medical assistance in ending their own lives was still at committee stage in the Lords when the house rose. Since it was introduced as a private member’s bill, it cannot be carried over into the next session.

Campaigners for assisted dying are furious at what they see as procedural obstruction by unelected peers, bogging the bill down with heaps of amendments and running down the clock , thwarting the will of the elected Commons. Critics of the bill counter that the normal legislative process was followed and that the volume of amendments was a function of poor drafting, leaving practical and ethical problems that had to be addressed in the Lords.

You can understand the motivation – more UK investment by UK funds means faster UK growth – but fiduciary duty trumps all

A simple principle lies at the heart of pension investment: the pension manager must invest in the best interest of the client. UK ministers have often wished UK funds would show more home bias by channelling more pensioners’ cash towards domestic assets in the interests of economic growth, but the fundamental rule of the game has always been understood. You don’t mess with the fiduciary duty.

Thus, when Rachel Reeves a year ago unveiled her Mansion House accord – a pledge by 17 of the biggest providers to earmark a slice of workplace pensions for UK private assets – it was made clear the arrangement was voluntary. What’s more, as the signatories emphasised, the commitment was “subject to fiduciary duty and the consumer duty” and “dependent on implementation by the government and regulators of critical enablers”.

Accusation vessel contains grain looted from Russian-occupied territories triggers diplomatic spat between both nations

Ukraine has asked Israel to seize a vessel it claims is carrying grain looted from Russian-occupied territories, triggering a rare diplomatic spat between the two countries.

The dispute spilt into public view this week when president Volodymyr Zelenskyy said that “another vessel” carrying grain “stolen by Russia” had arrived at a port in Israel and was preparing to unload.

• French driver struck animal while driving at 230 mph

• Peta says 40-year-old failed to show compassion for death

French racing driver Romain Grosjean has angered animal rights group Peta for “flippant” comments after hitting a bird while testing for next month’s Indianapolis 500.

The driver, who survived a fireball crash during the 2020 Formula One Bahrain GP, described the bird strike at around 230 mph in graphic terms this week.

While Unai Emery’s side are hoping to right past wrongs, their opponents are a serious threat under Vítor Pereira

It is eight years since Aston Villa and Nottingham Forest played out a Championship classic, a topsy-turvy 5-5 draw at Villa Park in which Tammy Abraham got four goals. John McGinn was also in the Villa side and Matty Cash scored to earn Forest a 3-2 lead with 22 minutes on the clock, before more drama ensued. Forest were reduced to 10 men but Lewis Grabban, who played for Villa the previous season, struck the final goal to earn a point.

It is the first top-flight meeting between the teams this millennium; however, that goes some way to telling the story of these sides, particularly Villa’s stealth. It was three and a half years ago, a couple of weeks before Unai Emery took the reins at Villa, and a glance at the teamsheet speaks volumes for the stability that has underpinned his success. Eight of Villa’s starting XI for that 1-1 draw could start against Forest on Thursday, when the Midlands clubs meet at the City Ground for the first instalment of an enticing all-Premier League Europa League semi-final. While there have been plenty of all-English finals, it is the first major European semi-final between English sides since Manchester United overcame Arsenal in the Champions League in 2009.

• Fears that Salah had played last game for Reds have eased

• Injury sustained against Palace found to be minor

Mohamed Salah is expected to play again for Liverpool before the end of his farewell season after being diagnosed with a minor muscle injury.

Salah was substituted in the 59th minute of Liverpool’s 3-1 win over Crystal Palace on Saturday with a hamstring problem. The 33-year-old’s reaction at the time – applauding all four sides of Anfield before heading straight down the tunnel – raised concerns that he was facing a lengthy spell on the sidelines and might have played his final game for the club.
