Mrs May defended last week's draft agreement for leaving the EU and said there was a "critical" week ahead.

She suggested agreeing more details of UK's future relationship with the EU, ahead of an expected summit next week, could satisfy the concerns of some of the Tory MPs opposed to her plans.

Ex-Brexit Secretary Dominic Raab said the UK was being "bullied" by the EU.

Labour leader Jeremy Corbyn said his party could get a better deal in time for Brexit, which is due to happen on 29 March.
