Sue fires back: “Paul, I think you have an appointment at Banalities R Us, just over there. Mary, we'll see you later.”

However a spokesperson for the show has dismissed the claims, insisting: "It's untrue, there was no tense exchange.”

This is Sue's final series hosting the show, after she declined to follow it to Channel 4 next year. Paul, however, will be making the move.

Speaking about his decision to remain on the show, Paul said earlier this week: 'What can I say? I'm still doing what I've always done.”

“I think for me, when they picked me to do the job seven years ago, I was really shocked that I was given the chance to do this programme,” he continued.

“To see it grow over the years. I just couldn't walk away from my job. I think it comes down to I love doing my job. I love evangelising about baking and passing the word on and I will carry on doing that.”
