Researcher Nathan Cofnas previously claimed Black people would hold few high-profile positions in a meritocracy

Nathan Cofnas, the academic who made plagiarism allegations against Prof Jason Arday before his death, has been suspended by a university.

Arday, 41, resigned from his role at the University of Cambridge this month after coverage of Cofnas’s accusations of plagiarism. The allegations, which were not proven in any formal investigation, triggered questions about Arday’s achievements.

Recycling system in Cambridgeshire that could save thousands of litres a day is deemed not in line with rules

The largest water reuse system in the UK, which could save thousands of litres of water a day for people living in one of the driest regions of the country, is not allowed to be switched on because of drinking water regulations.

As water supplies in England reach critical levels, the Guardian can reveal that a model water recycling system within an urban housing development in Cambridgeshire has not been switched on since it was made ready in 2021.

Amid the grief and rage at a tragic loss, it’s right to differentiate between those who fought a culture war and others who just sought the truth

Even now it is very difficult to process the scale of tragedy that engulfed Jason Arday and those who loved him. The unbearable sadness at his death; the wretched knowledge that the very public onslaught against him began with the malign machinations of a self-defined “race realist” – who believes that, in an ideal world, black people would “disappear from almost all high-profile positions outside of sports and entertainment”. The horror that a rightwing and far-right campaign seeking a victim to fuel its nativist prejudices can now crow that it found one.

There is wide and profound grief and of course there is rage, focused and unfocused. Both were on display as thousands joined a protest vigil in Trafalgar Square on Monday evening.

MPs, friends and campaigners gathered to remember former Cambridge professor after his death on Friday

Tens of thousands of people gathered in Trafalgar Square in London to remember and pay tribute to Jason Arday, the former Cambridge professor who died on Friday.

Stand Up to Racism, which organised the vigil, estimated that 30,000 mourners had gathered in the square to listen to emotional speeches from MPs, friends and campaigners on Arday’s life and legacy and join in a minute’s silence. Many were dressed in black and held flowers, which they were asked to leave beneath Nelson’s column. People also carried placards reading “rest in power”.

Calls grow for inquiry into media reporting of the case as Cambridge chancellor criticises ‘racist feeding frenzy’

A Windrush campaigner who launched a fundraiser for Jason Arday’s family has said the outpouring of support shows “Britain still cares”.

Arday, who was found dead on Friday, had resigned the previous week from his post as professor of sociology of education at the University of Cambridge after allegations of plagiarism were made against him.

University says it continued to provide support after resignation of academic, who was found dead on Friday

The University of Cambridge has defended its mental health support for the academic Jason Arday.

The university said it had continued to provide Arday with extensive mental health support and security measures, including installing panic alarms and screening racist emails and post, after he resigned from his post as professor of sociology of education this month.

Andy Burnham calls for reflection after ‘tragedy on so many levels’ in comments echoed by London mayor Sadiq Khan

Andy Burnham has called the death of Jason Arday, whose body was found at his home in south London on Friday, a “tragedy on so many levels”.

Arday resigned as a professor at the University of Cambridge last week after allegations of plagiarism, which he denied. He was pronounced dead just after 3pm on Friday.

Academic was pronounced dead at his home in south London after police called to address after 3pm on Friday

Jason Arday, the academic who resigned last week as a professor at the University of Cambridge, has been found dead at his home in south London.

The Metropolitan police said officers were called to Arday’s address by the London ambulance service after 3pm on Friday.

Vice-chancellor Deborah Prentice says she recognises the ‘difficult case’ has damaged the university

Cambridge University’s leadership has bowed to internal pressure for an independent investigation into its appointment of Jason Arday as a professor, with its vice-chancellor admitting the affair has damaged the institution.

Prof Deborah Prentice said she recognised the “anger and anxiety around this damaging and difficult case” but described it as an aberration that should not be used to cast aspersions on the abilities of its staff of colour.

Fellow pupils at his primary school have challenged Cambridge academic’s story, though others support it

The story of Jason Arday’s extraordinary rise to becoming the youngest black professor in the history of the University of Cambridge is all the more remarkable for one claim: that he did not learn to speak until just shy of his 12th birthday.

This claim was mentioned in a letter announcing his resignation last week, which came amid mounting questions about his academic work and statements he had made about his past.

Organoids and tissues grown from human cells promise more accurate results, with £20m Cambridge project to create standardised models

Group calls for ‘thorough and transparent investigation’ of hiring of professor who resigned after his claims came under scrutiny

The University of Cambridge has announced a review into the way it vets and hires senior academic staff in an effort to fend off external and internal criticism of its appointment of Jason Arday as a professor.

But a group of Cambridge academics quickly rejected the university’s response, saying: “We strongly believe that a thorough and transparent investigation into the wider circumstances of this damaging episode is essential.”

Serious failings by one academic, and his bosses at the University of Cambridge, should not be allowed to undermine wider progressive goals

Jason Arday’s resignation from the University of Cambridge on Wednesday marked a full stop of sorts, but not an end to the furore surrounding his promotion to a professorship at the age of 37. Academic colleagues have demanded, with justification, that an investigation into his appointment to the faculty of education in 2023, and the subsequent fallout, should include people from outside the university. Allegations of plagiarism and claims made by Mr Arday about his background, career and charity fundraising remain under scrutiny. The memoir for which he said he had received a huge advance, billed as a triumph over adversity including an early autism diagnosis, is scheduled to appear later this month. His publisher, Simon & Schuster, ought to pause while inquiries run their course.

But several things are already clear. By failing to do due diligence on Mr Arday before launching him, with fanfare, as Cambridge’s youngest-ever black professor, and through its inadequate response to later challenges, the university has done a serious disservice to black and neurodivergent scholars more widely. It has also set back the efforts of all the people and groups who have worked in good faith, over many years, to boost the presence of underrepresented groups in influential positions.

I can’t pass up the moment the Reform leader celebrates his byelection victory against ‘the establishment’ – a man with a dustbin on his head

You would have thought that after 35 years of writing for the Guardian I would have mastered some of the basics of holiday protocol by now. Apparently not. While I had remembered to let the newsdesk know I wouldn’t be writing the political sketch for two weeks, it had completely slipped my mind to inform the Saturday editor. So rather than leave her with the headache of an empty page, you’re getting an extra dose of me this week. And, in truth, I don’t mind because, for what is a usually empty August, there’s an awful lot still going on. I’ve even told the newsdesk that I’d like to write next Friday as I can’t pass up the moment Nigel Farage celebrates his byelection victory against the “establishment”, AKA a comedian with a dustbin on his head. This summer has been quite the reckoning for Reform. First some excellent investigative reporting from the Guardian and the Sunday Times, followed by even some of the party’s most loyal followers in the Spectator and the Telegraph beginning to turn. We will know the game is up when GB News begins to have doubts about Nige. It can only be a matter of time.

Exclusive: Academics call for inquiry, saying university must be held accountable for ‘grotesque racism unleashed’

The University of Cambridge’s leaders deserve blame for the “grotesque racism unleashed” by Jason Arday’s appointment as professor, according to academics calling for the university to hold an independent inquiry.

The Guardian understands that senior dons at Cambridge are circulating a joint letter calling for an inquiry into the processes and circumstances around Arday being given the position, with many suggesting the university wanted a “quick fix” to improve the diversity of its staff.

Simon & Schuster still plans to publish book by Cambridge academic who resigned this week amid plagiarism claims

Jason Arday, the former Cambridge professor accused of plagiarism and embellishment, claimed he was paid “1.4 million” for his forthcoming memoir detailing his extraordinary backstory.

Arday was dogged by a growing series of questions over his academic work and credentials before he resigned on Wednesday night, saying the “relentless accusations, speculation and public commentary have taken a profound toll on me and on those I love”.

From accusations of plagiarism to queries over his charity work, we list all the allegations against the academic

The rise and fall of Prof Jason Arday has been one of the most dramatic in the history of British academia. Diagnosed as autistic as a child, he says he was non-verbal until he was 11 and only learned to read and write at the age of 18. Less than 20 years later he was appointed the youngest black professor in Cambridge University’s history.

His resignation on Wednesday followed two weeks of intense scrutiny. He has been accused of plagiarism in his academic work and questions have been raised about a long line of claims about his backstory, from endurance running, footballing exploits and charity fundraising to academic positions, qualifications and authorship.

The Cambridge academic has rightly now resigned. But that won’t end the targeting of senior black figures or the lazy way institutions promote faux equality

‘To be honest with you, I thought you’d just believe me.” That was the breathtaking response of Prof Jason Arday when the Guardian interrogated the details he provided of an alleged racist campaign of intimidation against him, which involved a severed pig’s head, a masked man wielding a knife and bullets in the post. Arday had been unable to provide evidence, and when the Guardian contacted the relevant parties, including a south London butcher and the police, his claims were either refuted or could not be verified.

Arday, whose appointment as professor of sociology of education at Cambridge became a widely lauded moment in the aftermath of Black Lives Matter, has found himself in the eye of the storm. Allegations of extensive plagiarism in his doctoral thesis, completed at Liverpool John Moores University, recently made their way from the Substack of self-described “race realist” academic Nathan Cofnas into the national press. The defence of Arday had rested on the fact that an investigation had already been conducted, and cleared him of plagiarism. And yet the case has taken on a life of its own.

University says it has ‘new information’ about academic career of Jason Arday, the youngest black professor in its history

Jason Arday, the Cambridge professor accused of plagiarism and embellishment, is to face investigation by the university after it said it received “new information” about his qualifications and career.

Cambridge initially defended Arday – the youngest black professor appointed in the university’s history, with a compelling life story of educational disadvantage – as “the victim of a vile campaign”. But as questions mounted over Arday’s own claims, the university’s leaders felt that Cambridge’s reputation was in danger.

Jason Arday, the Cambridge professor accused of plagiarism and embellishment, has resigned after the university announced he was to face new investigations into his qualifications and career.
