Bannatyne, 66, is the one of oldest campers going into the jungle but he says age isn’t a concern for him at all.

The businessman said he climbed Mount Kilimanjaro aged 60 and added: “I was one of the oldest people in our group who did. A lot of the younger people who started pulled out. There were 25 of us at the bottom but only 19 of us got to the top.”

Also 66, Lady Campbell, who wrote a book about Diana’s affair with James Hewitt, revealed her eldest son didn’t want her to do the show because “he thought I was too civilised to do something like this”.

She said: “I am doing it for selfish reasons. It will help with the roof at the castle and I want to lose weight. I’d actually like to lose a stone if possible.”

She added that once she’d made the decision to do the show her son was, of course, “very supportive”.
