By Paul Taylor and Andreas Rinke BRUSSELS/BERLIN, July 5 (Reuters) - France and Germany called for an emergency summit of euro zone leaders to discuss Greece's stunning referendum vote on Sunday to reject bailout terms, as calls mounted in Berlin to cut Athens loose from Europe's common currency. German Chancellor Angela Merkel's deputy said Athens had wrecked any hope of compromise with its euro zone partners by overwhelmingly rejecting further austerity. Merkel and French President Francois Hollande conferred by telephone and will meet in Paris on Monday afternoon to seek a joint response.
