EU not expecting Britain to trigger Leave mechanism at summit

BRUSSELS, June 26 (Reuters) - The European Union does not expect British Prime Minister David Cameron to trigger the mechanism starting the process for Brexit negotiations when he meets other EU leaders at a summit on Tuesday, a senior EU official said on Sunday.

"We do not expect Prime Minister Cameron at this stage to trigger Article 50 on Tuesday," he said of the summit in Brussels where Cameron will brief leaders on the Leave vote at last week's British referendum on EU membership.
