Caroline Nokes, 37, a 'Cameron Cutie' who once boasted that she was too attractive to be a politician, had the personal support of David Cameron during her election campaign.
But she has heaped embarrassment on the Prime Minister by being caught enjoying a tryst in a hotel room with James Dinsdale, a Conservative activist ten years her junior.
Mrs Nokes and her husband Marc, 42, who have an 11-year-old daughter and celebrated their 15th wedding anniversary last week, refused to comment.
But the MP's young lover, a Conservative councillor and former leading light in the party's youth wing, Conservative Future, said: 'I can confirm Caroline Nokes and I have had a sexual relationship. I have no further comment to make.'
