A report into the behaviour of Gregg Wallace has substantiated 45 allegations made against the former BBC presenter, including claims of inappropriate sexual language and one incident of unwelcome physical contact.
A seven-month investigation into a series of allegations against the MasterChef presenter covered 83 allegations against him, with more than half substantiated by the investigation team.
Most of the substantiated allegations related to inappropriate sexual language and humour. However, an overview of the report said a "smaller number of allegations of other inappropriate language and being in a state of undress were also substantiated".
The production company Banijay and the BBC said the number of sustained allegations made Wallace's return to MasterChef untenable, despite his recent diagnosis of autism.
Wallace has already admitted using inappropriate language, but claimed to have been cleared of "the most serious and sensational accusations made against me".
The BBC confirmed Wallace would not be returning to its screens and admitted "opportunities were missed" to deal with his behaviour.
The report, overseen by the law firm Lewis Silkin, was ordered by MasterChef's producers Banijay last year after BBC News said it had heard allegations of inappropriate sexual comments and inappropriate behaviour by 13 people who worked with Wallace across a 17-year period. At that point, he stood back from his MasterChef role.
The investigation heard evidence from 78 witnesses, including 41 complainants. All the report's findings were linked to allegations made in connection to MasterChef.
It found the "vast majority" of the 83 allegations it heard (94%) related to behaviour that was said to have occurred between 2005 and 2018.
The report summary revealed that 10 other standalone allegations were made against other people, two of which were substantiated - one relating to swearing and one to racist language.
It found that 11 complaints or concerns had been raised about Wallace's behaviour between 2005 and last year. Some were raised with Banijay, others with the BBC. The majority were dealt with informally.
"The production company undertook an investigation into an allegation in 2015 and understood the complainant was happy with the outcome," the report said. "The BBC intervened in response to a complaint in 2017, following which Mr Wallace was warned of the need to change his behaviour. Mr Wallace took steps to heed that warning."
