David Mellor and Antonia de Sancha
David Mellor's extra-marital affair with the actress Antonia De Sancha became public knowledge after his mistress blew the lid, selling her story to the News of the World for £30,000 in 1992. There were a number of unsubstantiated allegations including those involving toe-sucking and a Chelsea football shirt, apparently propagated by PR wizard Max Clifford. But the truths were undeniable, as De Sancha had her property bugged and taped a number of incriminating conversations with the Conservative politician.
