The Isis fighter known as Jihadi Jack has been stripped of his British citizenship, prompting a diplomatic row between the UK and Canada, it has been reported. Muslim convert Jack Letts, 24, who had held dual UK and Canadian citizenship, declared he was an “enemy of Britain” after travelling from Oxfordshire to Syria at the age of 18 to join the terror group. He has begged to be allowed to return to the UK, insisting he had “no intention” of killing Britons, after he was captured by Kurdish forces in 2017. The Home Office has now stripped Letts of British citizenship, meaning he is the responsibility of the Canadian government, The Mail on Sunday said. It was reportedly one of the last actions of Theresa May’s administration.
