Oxford graduate and entrepreneur Freddie Fisher was one of the 16 contestants to enter the Big Brother house last Thursday.

Fisher's first task was to change his name by deed poll to ‘Halfwit' in order to stay in the house. The 23-year-old lives in a stately home, and doesn't own a TV. He claims not to know how the show works.

Fisher's time at Oxford was marred by controversy after it was revealed that he ran a website for rent boys, promising punters "fetish and role play". He lists his interests as "playing with fire, BB guns, trespassing."

An Oxford friend commented "Freddie had this crazy obsession with guns and weapons." A former Young Conservative, Fisher was recently pictured meeting Shadow Chancellor George Osbourne.
