'X'(born 15,April 1940) is an English author, actor, playwright and former politician. He was a Member of Parliament and deputy chairman of the Conservative Party, and became a life peer in 1992. His political career, having suffered several controversies, ended after a conviction for perverting the course of justice and his subsequent imprisonment.

While at Oxford,'X' made a name raising money for the then little-known charity Oxfam, obtaining the support of 'The Beatles' in a charity fundraising drive. The band accepted his invitation to visit the senior common room of Brasenose College, where they were photographed with 'X' and dons of the college, although they didn't play there. The critic Sheridan Morley, then a student at Merton, was present and recalled the occasion:
'At the interval I went to the toilet, and there beside me was Ringo Starr. He asked if I knew this 'X' bloke. I said everyone in Oxford was trying to work out who he was. Ringo said: 'He strikes me as a nice enough fella, but he's the kind of bloke who would bottle your piss and sell it.'

'X' was satirically portrayed as a misunderstood secret agent, saviour of Britain and mankind and "overall thoroughly good chap", by actor Damian Lewis in the BBC drama 'X': The Truth (2002),which received strong reviews. Script writer Guy Jenkin explained that "my 'X' is the man who has frequently saved Britain over the last 30 years. He's beloved of all women he comes across, all men, all dogs – he's a superhero".
