NewsNight's Kirsty Wark has made allegations against Gregg Wallace, who has stepped away from MasterChef after the BBC received a series of complaints

The Times reports a BBC boss at the broadcaster warned Wallace in 2017 his behaviour on set was “unacceptable and cannot continue”.

Broadcaster Kirsty Wark, who was a Celebrity MasterChef contestant in 2011, said he told "sexualised" jokes during filming. Wallace's lawyers say it is entirely false that he engages in behaviour of a sexually harassing nature. Masterchef's production company Banijay UK has launched an investigation and said Wallace is co-operating.
