PA MediaA celebrity episode of The Great British Bake Off featuring DJ Scott Mills will not be broadcast, Channel 4 has said.
The former Radio 2 breakfast show host was sacked by the BBC last month over a historic allegation of serious sexual offences.
Mills has said he "fully co-operated and responded" to an earlier police investigation, which didn't result in criminal charges, and did not want to comment further.
He had already filmed The Great Celebrity Bake Off for Stand Up To Cancer, but Channel 4 said it had "carefully considered the circumstances" and "taken the decision not to air" the episode featuring him.
"Acknowledging the seriousness of the accusations that have been made against Scott, we don't believe it would be appropriate to air the episode at this time," Channel 4 said.
"An alternative episode of Celebrity GBBO will go out in its place."
Mills had been due to feature in an episode of the baking competition alongside singer Rag'n'Bone Man, DJ Edith Bowman and JLS star Aston Merrygold.
No longer Boyzone support DJ
Meanwhile, Mills has also been removed from the line-up for Boyzone's two forthcoming concerts at Arsenal's Emirates Stadium in June.
He had been due to appear as the "special guest DJ" for both of the Irish boyband's Two For The Road reunion gigs.
But the broadcaster's name has now been removed from the bill. It is not clear whether he was removed or voluntarily dropped out of the shows.
In promotional material, Mills had previously been quoted as saying: "What a dream to support the lads this summer, it's going to be two nights of big tunes, big singalongs and plenty of 90s nostalgia. I hope you're ready!"
Fellow 90s pop groups S Club and B*Witched have also been announced as support acts.
'Stepping back' from charity
Mills has also stepped down as an ambassador for a multiple sclerosis charity, MS Society UK.
The DJ became an ambassador for the charity in 2015 when his mother was diagnosed with the progressive neurological condition.
A statement released by the charity on Tuesday said: "Scott Mills has been a valued MS Society Ambassador for over 10 years. In light of the current news, Scott is stepping back from this role while we review the situation.
"We take concerns of this nature and the trust placed in us as a charity extremely seriously. Our priority is the MS community and ensuring we can continue to support everyone living with and affected by MS."
Last week, children's cancer charity Neuroblastoma UK said it had decided to "part ways" with Mills, who had been a patron since 2021.
Mills was sacked by the BBC in March after it emerged the Metropolitan Police launched an investigation into the 53-year-old in 2016 over allegations of serious sexual offences said to have involved a teenage boy under 16 between 1997 and 2000.
The investigation was closed in 2019 after prosecutors decided there was insufficient evidence to bring charges.
The BBC said it was aware of a police investigation into allegations against Mills of a historical sexual offence in 2017, but sacked him last month after the corporation learned the alleged victim was aged under 16.
In a statement last week, Mills said: "An allegation was made against me in 2016 of a historic sexual offence which was the subject of a police investigation in which I fully cooperated and responded to in 2018.
"As the police have stated, a file of evidence was submitted to the Crown Prosecution Service, which determined that the evidential threshold had not been met to bring charges.
"Since the investigation related to an allegation that dates back nearly 30 years and the police investigation was closed seven years ago, I hope the public and the media will understand and respect my wish not to make any further public comment."
