The Government's Brexit Bill has been given the go ahead by parliament after two days of intense debate, by a majority of 384.
The passing of the bill gives Prime Minister Theresa May permission to trigger Article 50 and start formal Brexit talks.
MPs have historically voted by an overwhelming majority to give the Prime Minister permission to start the process of leaving the EU.
It will be a victory for Theresa May but a predicament for Labour's Jeremy Corbyn who ordered his party to vote with the government but a fifth of them defied him.
The next step is a government Brexit plan, a white paper, due to be published on Wednesday outlining details on leaving the single market and implementing a new trade agreement.
Residents in town which had the highest 'leave vote' in the referendum say Government's Brexit strategy "does not have enough detail".
Labour MP dodged questions over why she missed Brexit Bill vote in the Commons - by driving away from waiting reporters outside her home.
