Mary Berry, a beloved judge on The Great British Baking Show, decided to leave the show when it moved from the BBC to Channel 4 in 2016. The show underwent a change in production company and broadcasting network, and this transition led to several changes in the lineup of judges and hosts.
Mary Berry, along with hosts Mel Giedroyc and Sue Perkins, made the decision not to continue with the show out of loyalty to the BBC, which had aired the program since its inception in 2010. They felt that the move to Channel 4 would fundamentally change the nature and integrity of the show.
In an official statement at the time, Mary Berry expressed her decision to stay with the BBC out of loyalty, saying that she was "sad not to be a part of it" but wanted to remain with the public broadcaster. She also mentioned her fondness for the show and the privilege she had in being part of it from the beginning.
Following her departure from The Great British Baking Show, Mary Berry went on to host and judge other cooking and baking shows, including her own series, "Mary Berry's Country House Secrets" and "Mary Berry's Quick Cooking."
