UK's main opposition labour party calls for no-confidence vote in Theresa May

The leader of Britain's main opposition Labour Party will on Monday call for a no-confidence vote in Theresa May if the prime minister fails to name a date for a vote in parliament on her Brexit deal, a Labour source said.

The source made clear of the vote no confidence would be in the prime minister rather than her government. That means it would not be binding.
