Britain's chief censor at the British Board of Film Classification is leaving his post after 10 yearsThe British Board of Film Classification is in fresh need of a new pair of shears after its president, Sir Quentin Thomas, announced his resignation after 10 years in the role. Taking up the position in August 2002, Thomas was partly credited with ushering in a more open – and, critics claimed, more liberal era – at the BBFC, with controversial films such as Antichrist and Irreversible passed uncut for theatrical release."When I was appointed, Ali G said it was the best job in the world as you got to watch porn all day," Thomas, 68, said in a statement.
