LONDON Mayor Boris Johnson has provoked outrage, including from members of his own party and outside it, for saying Britons who travel to Iraq and Syria should be presumed guilty of terrorism.
He also suggested dropping a bomb on a British jihadist who appeared in an Islamic State execution video.
Shadow Business Secretary Chuka Umunna has said he doesn't think Boris Johnson's comments about returning British extremists are "sophisticated, sensible or responsible".
Liberal Democrat leader Nick Clegg said: “I’ll listen to security services rather than Boris when it comes to dealing with Islamic State militants.”
Shami Chakrabarti, Director of Liberty said: "When Mr Johnson was seeking the vote in London, he spoke passionately against identity cards and punishment without trial. Now his political ambitions have escalated, it seems that liberty is trivial and suspicions should replace charges, evidence and proof.
"Stripping Britons of their nationality is unjust to the innocent and internationally irresponsible if they are guilty. Control orders are anti-terror asbos that serve neither justice nor security. An August cockfight between rivals for the Conservative leadership is no way to make policy."
