MPs have backed Prime Minister Boris Johnson's plan for the UK to leave the EU on 31 January.They voted 358 to 234 - a majority of 124 - in favour of the EU (Withdrawal Agreement) Bill, which now goes on to further scrutiny in Parliament.The bill would also ban an extension of the transition period - during which the UK is out of the EU but follows many of its rules - past 2020.Earlier, Boris Johnson argued that it would allow the UK to "move forward".Labour leader Jeremy Corbyn told his MPs to vote against it, saying there was "a better and fairer way" to leave the EU.The government insists a trade deal with the EU can be in place by the end of the transition period, but critics say this timescale is unrealistic.The bill had been expected to pass easily after the Conservatives won an 80-seat majority at last week's general election.MPs also backed the timetable for further debate on the bill over three days when they return after the Christmas recess - on 7, 8 and 9 January.The government says it will get the bill into law in time for the 31 January Brexit deadline.The legislation, which would implement the Brexit agreement the prime minister reached with the EU in October, was introduced in Thursday's Queen's Speech, setting out the government's priorities for the next year.There are changes to the previous bill, which was backed by the Commons in October, but withdrawn by the government after MPs rejected a three-day deadline for getting it through Parliament.The changes include:

• Legally prohibiting the government from extending the transition period - during which a trade deal between the UK and EU will be discussed - beyond 31 December 2020

• Allowing more UK courts to reconsider European Court of Justice rulings that have been retained in UK law after Brexit

• Requiring ministers to report annually to Parliament on disputes with the EU under the prime minister's withdrawal agreement

• Repealing spent legislation that "now serves no purpose"

The bill also loses a previous clause on strengthening workers' rights.The government now says it will deal with this issue in a separate piece of legislation, but the TUC has warned that the change will help "drive down" working conditions.Beginning the debate in the Commons earlier, the prime minister said his bill "learns the emphatic lesson of the last Parliament" and "rejects any further delay"."It ensures we depart on 31 January. At that point Brexit will be done. It will be over," he told MPs."The sorry story of the last three years will be at an end and we can move forward."Mr Johnson said it also "paves the way" for a "ambitious free trade deal" with the EU.Labour leader Mr Corbyn said the government's "mishandling of Brexit" had "paralysed the political system," divided communities and was a "national embarrassment".He said MPs "have to respect the decision" of the EU referendum in 2016 "and move on"."However, that doesn't mean that we as a party should abandon our basic principles," he said."Labour will not support this bill as we remain certain there is a better and fairer way for this country to leave the EU."He said there had to be something better than this "terrible" Brexit deal that would not "sell out public services" or "sacrifice hundreds of thousands of jobs in the process".
