An investigation into Gregg Wallace’s “inappropriate behaviour” on MasterChef has found that more than half of the allegations against him have been substantiated, including one of “unwanted physical contact”.

MasterChef’s production company Banijay UK shared a summary of its report into historical allegations of misconduct against the 60-year-old presenter, carried out by independent law firm Lewis Silkin over seven months.

The report also said the number of sustained allegations made Wallace’s return to MasterChef “untenable”.

The investigation heard evidence from 78 witnesses, including 41 complainants.

There were 83 allegations against Wallace, and 45 of them were substantiated. All were related to MasterChef.

While the majority of the substantiated allegations related to inappropriate sexual language and humour, a smaller number of allegations of other inappropriate language and being in a state of undress were also substantiated.

One allegation of unwanted physical contact was substantiated.

Nearly all the allegations against Wallace were related to behaviour which is said to have occurred between 2005 and 2018, with just one substantiated allegation taking place post-2018.

Ahead of the publication of the summary, Wallace had said he had been “cleared of the most serious and sensational accusations” made against him.

Additionally, the report summary found that there were also 10 standalone allegations about other people between 2012 and 2018/2019, two of which were substantiated. Those people were not named in the summary.

The investigation found that complaints had previously been raised with the production company between 2005 and 2024.

While the report flagged inadequate reporting procedures prior to 2016, when Endemol merged with Shine ahead of Banijay acquiring Endemol Shine in 2020, it said there were significant improvements to HR processes and training after 2016.

While the investigation said some formal action was taken by the BBC in 2017, it also noted the corporation held no information regarding concerns raised over Wallace centrally, resulting in issues being addressed as a first offence.

Sky News has tried to contact Gregg Wallace for contact today.

BST Hyde Park festival has cancelled its final night after Jeff Lynne’s Electric Light Orchestra pulled out of the headline slot.

Lynne, 77, was due to play alongside his band on Sunday but has been forced to withdraw from the event following a “systemic infection”.

The London show was supposed to be a “final goodbye” from ELO following their farewell US tour.

Organisers said on Saturday that Lynne was “heartbroken” at being unable to perform.

A statement read: “Jeff has been battling a systemic infection and is currently in the care of a team of doctors who have advised him that performing is simply not possible at this time nor will he be able to reschedule.

“The legacy of the band and his longtime fans are foremost in Jeff’s mind today – and while he is so sorry that he cannot perform, he knows that he must focus on his health and rehabilitation at this time.”

They later confirmed the whole of Sunday’s event would be cancelled.

“Ticket holders will be refunded and contacted directly by their ticket agent with further details,” another statement said.

US rock band The Doobie Brothers and blues rock singer Steve Winwood were among those who had been due to perform to before ELO’s headline performance.

The cancellation comes after the band, best known for their hit Mr Blue Sky, pulled out of a performance due to take place at Manchester’s Co-Op Live Arena on Thursday.

ELO was formed in Birmingham in 1970 by Lynne, multi-instrumentalist Roy Wood and drummer Bev Bevan.

They first split in 1986, before frontman Lynne resurrected the band in 2014.

Donald Trump has said he is considering “taking away” the US citizenship of actress and comedian Rosie O’Donnell, despite a Supreme Court ruling that expressly prohibits a government from doing so.

In a post on Truth Social on Saturday, the US president said: “Because of the fact that Rosie O’Donnell is not in the best interests of our Great Country, I am giving serious consideration to taking away her Citizenship.”

He also labelled O’Donnell, who has moved to Ireland, as a “threat to humanity” and said she should “remain in the wonderful country of Ireland, if they want her”.

O’Donnell responded on Instagram by posting a photograph of Mr Trump with Jeffrey Epstein.

“You are everything that is wrong with America and I’m everything you hate about what’s still right with it,” she wrote in the caption.

“I’m not yours to silence. I never was.”

O’Donnell moved to Ireland with her 12-year-old son in January after Mr Trump had secured a second term.

She has said she’s in the process of obtaining Irish citizenship based on family lineage and that she would only return to the US “when it is safe for all citizens to have equal rights there in America”.

O’Donnell and the US president have criticised each other publicly for years, in an often-bitter back-and-forth that predates Mr Trump’s move into politics.

This is just the latest threat by the president to revoke the citizenship of someone he has disagreed with, most recently his former ally Elon Musk.

But the two situations are different as while Musk was born in South Africa, O’Donnell was born in the US and has a constitutional right to American citizenship.

Amanda Frost, a law professor at the University of Virginia School of Law, said the Supreme Court ruled in a 1967 case that the fourteenth amendment of the constitution prevents the government from taking away citizenship.

“The president has no authority to take away the citizenship of a native-born US citizen,” he added.

“In short, we are nation founded on the principle that the people choose the government; the government cannot choose the people.”
