Brexit timetable: What happens next in Britain's exit from the EU?

Brexit moved a step closer after MPs voted for the first time in favour of legislation to pave the way for Theresa May to trigger the formal process of leaving the EU.

The European Union (Notification Of Withdrawal) Bill will allow the Prime Minister to invoke Article 50 of the EU treaties and was backed by 498 MPs to 114, a majority of 384, at second reading in the House of Commons, its first stage.

But Labour leader Jeremy Corbyn was unable to contain a revolt on his frontbench as two shadow cabinet ministers quit so they could defy his orders and vote against the Bill.
