As soon as she posted the tweet, Leith said, she thought: “Oh my God.”

“I went into a panic mode where I couldn’t work my phone and I didn’t know how to delete it quickly and I couldn’t think,” she said.

“In the end I just rang my trusty PA and she said, ‘I’ve already deleted it,’ and it was 89 seconds after I had done it and that was too late, it had been retweeted.”

Paul Hollywood, Leith’s fellow judge on Bake Off, said this week that he believed her tweet was responsible for a dip in viewing figures for the finale. However, while there was some speculation about whether Leith would be invited back to the show, Channel 4 has already confirmed she will be returning.

In a statement released earlier this month, Channel 4 CEO Alex Mahon said that it was “testament to the phenomenal appeal of The Great British Bake Off that almost nine million people watched Sophie triumph as Channel 4’s first ever Bake Off winner”, even after Leith’s revelation.

Faldo herself, meanwhile, has said that she has “no hard feelings” about Leith’s mistake.

Shortly after her victory was officially announced, 2017’s star baker told BBC Newsbeat: “All it meant for me was that everyone knew a little bit too early.

“I really do feel bad for Prue because she must be feeling terrible about it.”
