Jeremy Corbyn says Labour will back another EU referendum after his alternative Brexit plan was again defeated in the Commons.
But the Labour leader said he will also continue to push for "other available options" including a general election.
He is facing calls from pro-EU Labour MPs to throw his full weight behind another referendum.
It came as MPs voted to endorse Theresa May's Brexit strategy - but only after she made a series of concessions.
The PM also faced a Brexiteer rebellion, after 20 Tory MPs voted against proposals, backed by the government, to delay the UK's 29 March departure date if there is a no-deal scenario.
Labour's Brexit proposals - which would see the UK join an EU customs union - were defeated by 323 votes to 240, a bigger margin than the last time MPs voted on them.
In a statement, Mr Corbyn said: "We will back a public vote in order to prevent a damaging Tory Brexit or a disastrous no deal outcome.
"We will also continue to push for the other available options to prevent those outcomes, including a close economic relationship based on our credible alternative plan or a general election."
Shadow Brexit Secretary Sir Keir Starmer tweeted that Labour will "put forward or support an amendment in favour of a public vote to prevent a damaging Tory Brexit."

'No majority'
Former shadow cabinet minister Owen Smith, a longstanding critic of Mr Corbyn, said: "Now that Labour's version of Brexit has been rejected by Parliament, I expect Jeremy Corbyn to throw his full weight behind campaigning for a Public Vote."
Labour MP David Lammy, a supporter of the Best for Britain campaign for a second referendum, said: "It's become clear today that there is no majority in the House for May's deal, but also that Labour's alternative plan cannot command a majority either.
"In the key votes ahead of us we must extend Article 50 to take a catastrophic no-deal off the table and use that time to put this decision back to the people to decide if they back the government's botched Brexit deal or staying in our current EU deal."
But Labour former minister Caroline Flint said the party should not back a second referendum despite the defeat of Mr Corbyn's plan.
She said: "I think the British public want us to get on with this and sort out a deal that works."
She said Labour's leadership should "engage in negotiation, to use the leverage you have got, to get a better deal".
Brexiteer rebellion
MPs also rejected an SNP motion saying the UK should not leave the EU without a deal "under any circumstances" - by 324 votes to 288.
Labour MP Yvette Cooper's amendment, which the government supported, was backed by 502 votes to 20, with a small group of Tory Brexiteers voting against it.
The amendment contained Theresa May's commitment on giving MPs a vote on delaying Brexit if both her deal and no-deal are rejected by MPs.
Mrs May announced this policy as she promised MPs a meaningful vote on her deal by 12 March - just 17 days before the UK is set to leave the EU.
The move was designed to head off a possible defeat when MPs voted on Ms Cooper's amendment.
Ms Cooper did not drop her amendment, because she wanted to hold Mrs May to her word - although the government has said it accepted the proposal.
Conservative MP Alberto Costa's amendment, which seeks to protect the rights of UK citizens in the EU and vice versa, even if there is a no-deal Brexit, was accepted by the House without a vote, after the government said they supported it.
Mr Costa said he was still forced to resign as an aide to Scottish Secretary David Mundell because of a convention that members of the government cannot table amendments to government motions.
Conservative MP Caroline Spelman opted not to put her amendment - calling for the PM's promise to give MPs a vote on delaying Brexit to be made legally binding - to the vote, after reassurances by the government.
