The "no" vote won by a hearty margin — 391 to 242, forcing another parliamentary vote on Wednesday on whether to back a "no-deal" Brexit. Wednesday's vote will be a free vote for the Conservative Party — that is, members will vote according to their conscience rather than on party lines.
May said that although it's crucial that the U.K. secures a deal, she is committed to honoring the 2016 referendum. Therefore, the default remains that the U.K. will leave the European Union without a deal regarding new trade practices.
If members of Parliament vote against a "no-deal" Brexit, then there will be yet another vote on Thursday, in which MPs will vote to extend article 50, which all of Parliament hopes to avoid.
Labour Party leader Jeremy Corbyn and Ian Blackford, the Scottish Nationalist Party leader at Westminster, said that May's second defeat was grounds for a general election and a second Brexit referendum, respectively.
