In response to her fellow judge Paul Hollywood’s decision to remain on GBBO, Mary declared that she would always “stand by him,” but also added, “Paul and I had our differences about what was important to us.”

Paul explained why he was returning to the show in a statement of his own. “It’s been a huge part of my life in the past few years and I just couldn’t turn my back on all that,” Paul shared. He later went on to thank Mary in a tweet.
