Brexit: What happens next?
Britain's parliament has demanded that Prime Minister Theresa May renegotiate a Brexit divorce deal that the other members of the European Union say they will not reopen.
Less than two months until the United Kingdom is due by law to leave the EU, the options include a disorderly Brexit, a delay to Brexit or no Brexit at all.
Below is a summary of what is due to happen next:
MAY MEETS CORBYN
Opposition Labour leader Jeremy Corbyn, who had refused to hold talks on Brexit with May, said after the vote on Tuesday night that he was now prepared to meet with her.
That meeting is due to take place at 1500 GMT on Wednesday, with a source in his party saying Corbyn would tell May a no-deal exit must be taken off the table and she should pursue his party's "alternative plan" for Brexit.
May's Conservatives do not have a majority in parliament and many of her own lawmakers and the small Northern Irish Party which props up her government oppose her deal as it stands, so winning the support of Labour would help ensure she can get it through parliament.
The meeting is not expected to result in a breakthrough.
MAY SPEAKS TO LAWMAKERS
On Tuesday, lawmakers backed a symbolic call on the government to stop a potentially disorderly no-deal exit, sending a signal that most oppose such a departure. It does not bind the government but May said she would talk to lawmakers to discuss how that outcome could be prevented by securing a deal which parliament could support.
May also said she would engage seriously with a compromise plan put forward by Conservative lawmakers which seeks to draw a line under internal divisions that have so far prevented parliament approving a deal.
It courts Brexiteers with a promise to ditch an unpopular Irish border policy in favour of an alternative, and appeals to remain-supporting Conservatives by pledging safeguards against the risk of disruption if no deal can be agreed with the EU.
MAY SPEAKS TO EU LEADERS
May has said she will speak to the EU to seek the changes demanded by parliament, but she has no confirmed plans to travel to Brussels yet.
EU27 ambassadors are due to meet on Wednesday to discuss Brexit, and May will speak to European Council President Donald Tusk by phone at 1745 GMT on Wednesday.
On Tuesday Tusk said the divorce deal was not up for renegotiation.
May will also speak to Irish Prime Minister Leo Varadkar later on Wednesday.
NEXT VOTE IN UK PARLIAMENT
May said the government would bring a revised deal back to parliament for a vote as soon as possible. Before the previous vote, parliament held five days of debate but it is not clear whether there would be another lengthy debate before any subsequent vote.
May said that if she did not bring a deal back for a vote by Feb. 13, she would make a statement to parliament and put forward a motion for debate on Feb. 14. Lawmakers will be able to put propose amendments to that motion.
An attempt by Labour lawmaker Yvette Cooper and Conservative Nick Boles to give parliament the power to request a delay to Britain's March 29 exit was defeated by lawmakers on Tuesday, but Boles said he would renew that effort on Feb. 14 if a deal has not been passed by then.
"We remain committed to ensuring that we don't reach the cliff edge on 29 March without a deal," Boles and Cooper said in a statement on Tuesday.
May also said that if she brings a deal back for a vote and it is rejected, she will put forward a motion the following day which lawmakers will be able to propose amendments to.

EU SUMMIT
All EU leaders are due to meet in Brussels on March 21-22. This could be an oppportunity for an eleventh-hour deal, or it would be the last chance to agree an extension of the Article 50 negotiation period and delay Brexit to avoid no-deal disruptions.
EXIT DAY?
If May does not get a deal approved by parliament by March 29, Britain faces a disorderly exit, or may be forced to seek an extension of Article 50 to give more time to reach an agreement. It is not certain the EU would agree to this.
Some lawmakers, including Labour leader Corbyn, have said it is now "inevitable" that the government will have to seek an extension regardless, as there will not be enough time to pass the necessary legislation for Britain's exit before March 29.
