The inquiry, executed by the law firm Lewis Silkin, concluded that out of 83 allegations filed against Wallace, 45 were substantiated. These allegations span a timeframe from 2005 to 2024, addressing various concerns including Wallace being inappropriately undressed and instances of unwanted physical advances. Many claims highlighted "inappropriate sexual language and humor," and some also cited culturally and racially insensitive remarks.

The investigation involved interviews with 78 witnesses and took seven months to complete. According to Banijay, the production company behind "MasterChef," the weight and consistency of the allegations made Wallace's return to the show “untenable.”

In response to the BBC's decision, Wallace took to Instagram to deny many of the claims, although he did acknowledge that some of his jokes and language could have been deemed inappropriate. In a now-deleted post, he stated, "I recognize that some of my humor and language, at times, was inappropriate. For that, I apologize without reservation." He described his public persona as that of a "cheeky greengrocer" and expressed that in today's context, his character is misconstrued as problematic.

The future of both Wallace and the show hangs in the balance as reactions pour in from audiences and stakeholders alike.
