London's mayor Boris Johnson has thrown his weight behind the campaign for Britain to leave the European Union, in a blow for his old friend and rival Prime Minister David Cameron who had appealed for his backing. "After a great deal of heartache… I will be advocating vote 'Leave'," Johnson said, making his long-awaited announcement to a large crowd gathered outside his home in north London. Johnson, a popular politician from Cameron's Conservative Party who is seen as a potential successor to the British premier, said he wanted ties with Europe based on "trade and cooperation" and not "a political project".
