After Theresa May's Withdrawal Agreement was rejected in her third attempt to get it through Parliament last week MPs will today vote on a number of alternatives in a second round of indicative votes.
Where does this leave the Brexit process? Is the Prime Minister going to have to resign soon? Read on to find out.
What happens next?
Today MPs will have their say in a second round of indicative votes to try to find an alternative they prefer after failing to back any of the eight options put to them last Wednesday.
The options that were rejected by the smallest margins were a so-called "confirmatory referendum" and a customs union, with 268 MPs backing the former and 264 going for the latter. Ideas relating to that - or perhaps combining both - will be on the cards.
Many of last week's eight options have returned for round two, but some have been replaced with new alternatives.
If they fail to reach a conclusion yet again, Jeremy Corbyn will continue pushing for a general election.
Mrs May has said that she fears "we are reaching the limits of the process" given how many options MPs have rejected, so she could sympathise if MPs fail to come up with another option.
Voting is expected to begin at 8pm
Is Mrs May about to resign?
The Prime Minister has made clear she was not going anywhere yet. She told MPs she would keep pressing "the case for an orderly Brexit" in her quest to deliver on the referendum result, suggesting she could even try to push for a fourth vote on her deal.
Of course, if she fails, or MPs force her to pursue too soft a Brexit, she could well be pushed to the brink of resignation.
How soon does the UK have to come up with a way forward?
The UK has just under two weeks to come up with a plan. This is because the House of Commons' failure to ratify a deal this week means that Article 50 has only been delayed until April 12.
Donald Tusk has indicated that he will call a European Council summit ahead of it on April 10, so the UK will need to be able to make clear in advance what it intends to ask European leaders for next.
In view of the rejection of the Withdrawal Agreement by the House of Commons, I have decided to call a European Council on 10 April. #Brexit

But what happens then? Will the EU agree?
Sources both in Germany and the European Commission say they are very confident that a long extension will be granted, provided that Mrs May offers a clear path through the deadlock.
This would be either a general election, a second referendum or - in a move that Berlin believes could be the next best step - another round of indicative votes geared to tease out a majority in the Commons.
For example, several popular indicative vote proposals - such as the Common Market 2.0 idea, the customs union, and the second referendum, could be rolled into one.
Meanwhile, options that favour a hard Brexit, or no deal, could be folded together as a different proposal.
Whatever the chosen way forward, the EU would allow the UK as much time as it needs to run the required votes or campaigns.
What if May turns up with nothing?
It is feasible - perhaps even likely - that Mrs May does not have enough time or power to come up with the "deep political change" the EU has cited as a condition of an extension.
This scenario would ruffle the feathers of French president Emmanuel Macron, who is taking an increasingly hard line against the UK.
At the last EU summit, it was France that had to be carefully and sensitively talked down, mainly by Poland, from pushing the UK into a 'no deal' scenario.
Mr Macron wouldn't be the only leader tearing their hair out of Mrs May failed to provide a new proposal.
The Netherlands, usually a close ally of the UK, is beginning to feel "despondent" about the latest twist in the process, according to one source.
