MPs voted to authorise Theresa May to seek a Brexit delay until 30 June, amid fresh warnings from France and Germany over the details of any extension.
The prime minister personally appealed to Angela Merkel and Emmanuel Macron during meetings on Tuesday, while European Council president Donald Tusk said there was “little reason to believe” Brexit could be sorted by June.
His comments come ahead of a crunch Brussels summit on Wednesday, at which EU leaders will decide whether to approve the prime minister’s request or offer a longer delay.
All 27 remaining EU heads of government must agree to an extension if the UK is to avoid the default position of a no-deal Brexit on Friday night.

Theresa May heads to Paris to plead for Brexit extension amid Tory fury in London
Conservative anger at the prime minister's plan to seek a further extension bubbled over at Number 10"There is a point here to distinguish between the talks with the Labour Party that are ongoing and what will inevitably happen when we bring a withdrawal agreement through the Commons is that somebody will bring forward an amendment on whether there should be a confirmatory referendum."
"It has been made clear to me that is not government policy."My issue with that is that a week ago we were given free votes and I was allowed to vote for this concept of putting the prime minister's deal back to the people to get it through."
He said it would be the "politics of the madhouse" if the government allowed a free vote but then sacked MPs for explaining why they voted the way they did.
He said:
"If I then get sacked for actually explaining the way I voted in a free vote, that to me would be a new low in democracy".
"It would be nonsensical for me to be given a free vote, to be allowed to vote the way I wish to vote, but then to explain it I would lose my position.
"That's politics of the madhouse and I am just not willing to go along with that."

Justice secretary David Gauke also says 'too early' to tell whether Jeremy Corbyn-Theresa May talks will produce an agreement
"EU leaders this week are open to an extension, but they certainly want to see a plan to go with that extension, so that everybody knows that the time is being used to try to conclude the first phase of Brexit, which requires the ratification of the Withdrawal Agreement and, if necessary, changes to the future relationship declaration."
He said EU leaders welcomed Ms May having "moved onto a new path" by opening talks with Labour, adding:
"She has reached out to the Labour Party. These talks are serious. My information is that the two parties are talking very seriously to each other.
"There isn't an outcome yet, that's pretty clear. But I think what leaders will want to hear from the British prime minister is that there is either some agreement or else a serious process under way that has a realistic chance of success.
"What I mean by that is a middle-ground position that can command a majority in Westminster, which of course hasn't been possible to date."
"We would be stuck in the worst of both Worlds, not only unable to set our own international trade policy but subject, without representation, to the policy of an entity over which MPs would have no democratic control.
This is something that Labour do not presently seem to understand. As I said at the meeting, in such a scenario the UK would have a new role in the global trading system.
As I said at the meeting, in such a scenario the UK would have a new role in the global trading system - we ourselves would be traded. As the famous saying in Brussels goes, if you are not at the table, you are on the menu."
"It's in the Dutch interest to avoid a hard Brexit and if more time will be needed to avoid a hard Brexit we should allow for more time.
Most important is that the UK makes clear what solution they will offer to avoid a hard Brexit.
Until now we only have the request for an extension but we are hoping for a specific plan from the UK side of how to avoid a hard Brexit."
"The Withdrawal Agreement is not going to be reopened, is not up for negotiation again. That continues to be the case.
"The Political Declaration, which will set the framework for future relations, can be improved, we can provide an increased level of ambition if that is the wish of the UK.
"There is one point that needs to be stated quite clearly and that is that these ambitions for the future relationship, which could - for example - consist of adding to the free trade agreement on which we have agreed with the UK already a customs union, a genuine customs union.
"We are willing to improve and amend the Political Declaration rapidly, within a few hours or days."
“The UK has asked for an extension. The French position hasn't changed. We consider this demand is neither agreed nor automatic. It's very important it comes with a credible political plan which will pass during the extension.
We want to understand what the UK needs this extension for and what is the political surroundings to have this extension. Then comes the question of the conditions; what role the UK wants to play during this extension time, how does it want to decide."
