Greg Wallace hosted MasterChef for 20 years, but stepped away from presenting the show last year after facing a string of misconduct claims, first revealed by BBC News.
The show’s production company Banijay ordered an inquiry, which heard 83 allegations against the TV presenter.
Of those, 45 were upheld, including one of unwelcome physical contact and three of being in a state of undress. Most related to inappropriate sexual language and humour, and also culturally insensitive or racist comments.
In response, he said he was “deeply sorry for any distress” he caused and that he “never set out to harm or humiliate”, but that “none of the serious allegations against me were upheld”.
A separate claim that his co-host John Torode had used a severely offensive racist term was also substantiated. Torode has said he has “no recollection” of the incident.
Both presenters were sacked in July.
In September, it was revealed that food critic Grace Dent and chef Anna Haugh are the new hosts of MasterChef.
