Brexit talks over: UK Labour leader calls time on discussions with PM May

LONDON (Reuters) - Britain's opposition Labour Party leader Jeremy Corbyn has written to Prime Minister Theresa May to say talks over breaking the Brexit impasse "have gone as far as they can go" because of the instability of the government. Corbyn said the Conservative Party's moves toward selecting a new leader means the government has become "ever more unstable and its authority eroded” undermining confidence in the "government's ability to deliver any compromise agreement".
