London: British MPs have again failed to agree on proposals for the next steps in the Brexit process.
The Commons voted on Monday four motions for leaving the EU, including a customs union and a Norway-style arrangement -- keeping the UK in the single market -- but none gained a majority, the BBC reported.
The votes were not legally binding, so the government would not have been forced to adopt the proposals.
The plan Theresa May negotiated with the EU has been rejected three times.
May now has until April 12 to either seek a longer extension from the EU to take a different course or decide to leave the EU without a deal.
She will meet her cabinet on Tuesday morning to discuss what to do next.
The option defeated by the narrowest margin was a proposal for a customs union, losing by only three votes.
That would see the UK remain in the same system of tariffs - taxes - on goods as the rest of the EU -- potentially simplifying the issue of the Northern Ireland border, but preventing the UK from striking independent trade deals with other countries.
The motion calling for a confirmatory referendum received the most votes in favour, totalling 280, but still lost by a margin of 12.
Following the failure of his own motion to stay in the Single Market - known as Common Market 2.0 - Nick Boles resigned from the Conservative Party.
In a point of order following the results, the MP for Grantham and Stamford said he could "no longer sit for this party", adding: "I have done everything I can to find a compromise."
As he left the Commons, MPs were heard shouting, "don't go Nick", and others applauded him.
He later tweeted that he would remain an MP and sit in the Commons as "an Independent Progressive Conservative".
Brexit Secretary Stephen Barclay said the "only option" left was to find a way forward that allows the UK to leave the EU with a deal.
"The government continues to believe that the best course of action is to do so as soon as possible," he said.
"If the House is able to pass a deal this week it may still be possible to avoid holding European elections."
Labour leader Jeremy Corbyn said it was "disappointing" that none of the proposals secured a majority, but he said he wanted to remind the Commons that Mrs May's deal had been "overwhelmingly rejected".
He added: "If it is good enough for the prime minister to have three chances at her deal, then I suggest it's possible the House should have a chance to consider again the options we had before us... so the House can succeed where the prime minister has failed - in presenting a credible economic relationship with Europe for the future that prevents us crashing out with no deal."
