More than 50 public figures have added their names to a letter in the Guardian newspaper saying the Pope should not be given the "honour" of a UK state visit.
Authors Terry Pratchett and Philip Pullman and actor Stephen Fry are among those critical of the Vatican record on birth control, gay rights and abortion.
Stephen Fry told the BBC why he signed the letter.
