Former prime minister Tony Blair has left the Anglican Church to become a Roman Catholic.
His wife and children are already Catholic and there had been speculation he would convert after leaving office.
Last year, Mr Blair, who is now a Middle East peace envoy, said he had prayed to God when deciding whether or not to send UK troops into Iraq.
And one of Mr Blair's final official trips while prime minister was a visit to the Vatican in June where he met Pope Benedict XVI.
