Theresa May faced the wrath of Tory Brexiteers as she addressed parliament after sealing a six-month extension of the UK's EU membership.
The prime minister insisted she would not resign after European leaders agreed to delay Brexit until 31 October in late-night talks in Brussels.
The second delay to the Brexit process - initially intended to conclude on 29 March - averted a no-deal withdrawal on Friday with less than 48 hours to go.
However, it infuriated anti-EU Conservative MPs, who insisted the UK should have instead left the EU without a deal.
As she updated MPs in the Commons, Ms May faced calls from veteran Tory Sir Bill Cash to step down. He accused her of an “abject surrender” and asked if she would resign. Ms May replied: “I think you know the answer to that”.
Another Brexiteer, Peter Bone, asked the prime minister if she planned to “honour” her vow not to delay Brexit beyond 30 June.
But the prime minister insisted she could still get a Brexit deal through parliament and said cross-party talks with Labour must “press on at pace”.
It came after a marathon European Council meeting to discuss the UK's request to delay Brexit until 30 June. Most EU leaders had wanted a much longer extension but settled on the date of 31 October after strong opposition to a lengthy delay from French president Emmanuel Macron.
Afterwards, Council president Donald Tusk admitted it was his “quiet dream” that the UK would remain in the EU.

Good morning and welcome to The Independent's live coverage as Theresa May prepares to address MPs after agreed a six-month delay to Brexit.
The prime minister is likely to face anger from Conservative backbenchers in the Commons after European leaders agreed to extend the UK's membership of the EU until 31 October.
In a press conference in the early hours of Thursday, European Council president Donald Tusk did not rule out further extensions beyond October.
And he sent a message to the UK: "This extension is as flexible as I expected, and a little bit shorter than I expected, but it's still enough to find the best possible solution.
"Please do not waste this time."
Theresa May is set to enrage her critics within the Conservative party after setting herself up to stay on as prime minister until the winter while presiding over a long delay to Brexit, writes our Europe correspondent Jon Stone. Here's the full story:

EU leaders agree Brexit delay until end of October as May blames MPs for stopping UK departure
PM will only quit when withdrawal agreement is approved, downplays effect of long delay"It is not a secret that we have had a difficult time in trying to get the deal through the House of Commons.
"Parliament is in gridlock at the moment and I think that we have got the time, hopefully, to get the deal through.
"But it's been challenging.
"I think that the extension is long enough to get a deal through."

EU Council president says 'maybe we can avoid the UK leaving - it's my quiet dream'
In a dramatic night in Brussels, European leaders rebuffed Theresa May’s calls for a short extension to 30 June"The government is certainly willing to discuss a customs union, but a customs union would require to command a majority of support in Parliament.
"A customs union has been put forward previously in parliament and hasn't commanded a majority, partly because we've had the usually politicking, the SNP who say they support a customs union then didn't vote for it.
"So nothing that goes forward will actually be successful unless we can command majority support for it in parliament."

"Julian Assange, 47, has today, Thursday 11 April, been arrested by officers from the Metropolitan Police Service (MPS) at the Embassy of Ecuador, Hans Crescent, SW1 on a warrant issued by Westminster Magistrates' Court on 29 June 2012, for failing to surrender to the court.
"He has been taken into custody at a central London police station where he will remain, before being presented before Westminster Magistrates' Court as soon as is possible.
"The MPS had a duty to execute the warrant, on behalf of Westminster Magistrates' Court, and was invited into the embassy by the Ambassador, following the Ecuadorian government's withdrawal of asylum."
The poll for the British Association for Counselling and Psychotherapy (BACP) found that 33 per cent of people said Brexit had impacted their mental health and wellbeing, while an additional 24 per cent said it had "a little" effect.
Labour and Liberal Democrat voters were more than twice as likely to say this was the case.
Andrew Kinder, a counsellor and BACP governor, said:
"Most of us dislike change, because of the uncertainty it creates, and there is a lot of uncertainty around Brexit.
"There is uncertainty on whichever side people voted for, whether that is Remain or Leave.
"Uncertainty can be stressful for people, and it does impact on their wellbeing, and if people have underlying issues as well, this is fuelling it and adding to it."

Opinion: The Halloween Brexit extension confirms it – we are never leaving the EU
The postponement of the Brexit deadline to October, agreed by EU leaders last night, suggests that leaving the EU is just too difficult"We wanted to have the unionist voice heard so that he could hear the impact of the backstop and what it will do to the balance in Northern Ireland.
"We had good engagement around that issue today."
She refuses to be drawn on whether she has confidence in Theresa May, saying only:
"As you know, the confidence and supply agreement that we signed was with the Conservative Party and whoever the leader of the party is we will work with. We believe in national stability. We want to see Brexit delivered."
Ms May, who will deliver a statement in the Commons on Thursday, told MPs weeks ago that she was “not prepared to delay Brexit any further than 30 June” as prime minister and would resign once this stage of talks was complete.
