(27.3.2016) A British exit from the European Union would significantly weaken the bloc‘s security, David Petraeus, a former U.S. military commander and CIA director wrote on Sunday, urging Britons not to vote to leave the union at a June referendum.

The comments, days after suicide bomb attacks killed 31 people in Brussels, support one of the British government‘s key arguments in its campaign to win over undecided voters – that the country is safer inside the 28-country bloc.
