May will attend the EU Council summit where she will ask for Article 50, the two-year withdrawal process, to be extended.
Goldman said it saw the probability of a no-deal exit at 15 percent and the probability of no Brexit at around 35 percent.
British lawmakers voted on Thursday night to allow the government to seek a delay for Britain's departure from the bloc.
"What is also government policy is to leave with a good deal and that is what we have". Options include a long delay, exiting with Mrs May's deal, leaving without a deal or even another referendum.
A spokesman for the European Commission said extending Article 50, the mechanism taking the United Kingdom out of the EU on 29 March, would need the "unanimous agreement" of all EU member states.
And I'll leave you with a thought, the Tory Manifesto promising us an European Union referendum came out in April 2015, which is now four years ago. According to the Washington Post, Corbyn's spokesman states that Prime Minister Theresa May is "recklessly running down the clock" forcing "MPs to choose between her botched deal and a disastrous no-deal". In previous political eras, by now she would probably have quit as prime minister or been forced out of office.
Labour's John McDonnell indicated that MPs would "move heaven and Earth" to block a no-deal Brexit and continued to suggest the party could back a call to put a Brexit deal to a public vote.
"There will be Conservatives who vote against it come what may, that's why in order for it to pass three things have to happen: she has to get the DUP on board, she has to persuade as many as possible of the 75 (Brexiteer) Conservatives to vote for it, and she will nearly certainly need more Labour MPs", said John Whittingdale, a Conservative lawmaker and member of the pro-Brexit faction.
Leading hundreds of people in the protest, Nigel Farage said: "The will of the people is very clear".
The amendment has also drawn support from Conservative MPs, with former minister Phillip Lee a lead signatory.
Any delay will require the agreement of all other 27 European Union members, with talks about possible conditions for an extension to take place before next week's European Union summit, which begins on Thursday. However this will require unanimous agreement from the 27 leaders, which is not guaranteed as the EU's chief negotiator and several leaders, including French President Emmanuel Macron, have said there would need to be a good reason given.
The 10 votes provided by the DUP, which props up the government, are thought to be key to the prime minister securing her deal.
