LONDON (REUTERS) - British lawmakers could be given a vote on a revised Brexit deal as soon as next week as negotiators in Brussels scramble to clinch last-minute changes to the divorce accord that would avoid a potentially disorderly exit from the European Union.
Unless Prime Minister Theresa May can get a Brexit deal approved by the British Parliament, she will have to decide whether to delay Brexit or thrust the world's fifth-largest economy into chaos by leaving without a deal on March 29.
When asked what would happen next week, Finance Minister Philip Hammond said: "There may be an opportunity to bring a vote back to the House of Commons - there may be an opportunity, but that will depend on the progress that is made in the next few days."
Mrs May, once a reluctant supporter of EU membership who won the top job in the political chaos following the 2016 referendum, has promised to give lawmakers a chance to decide what to do about Brexit on Feb 27 unless she can bring back a deal.
She pressed for "legally binding changes" at talks with European Commission President Jean-Claude Juncker on Wednesday.
Mrs May wants to prevent the "backstop" policy on the Irish border binding Britain indefinitely to EU rules.
Lawmakers on Jan 15 voted 432-202 against her deal, the worst defeat in modern British parliamentary history, largely due to the Irish backstop, which is intended to avoid new trouble in Northern Ireland.
With the clock ticking down to March 29, the date set in law for Brexit, the United Kingdom is ensnared in its deepest political crisis in half a century as it grapples with how, or even whether, to exit the European project that it joined in 1973.
Mr Hammond said Mrs May's talks with Mr Juncker had gone well.
"They were good and constructive talks yesterday," Mr Hammond said, adding that the two sides were talking about giving some guarantees that the Irish border backstop could only be a"temporary arrangement".
"That is a word that hasn't been used before and I think that is significant," he said. "Both sides have acknowledged that the political declaration could be expanded, for example, to address concerns that have been expressed in some parts of the House of Commons about workers' rights."
People close to the negotiations say discussions have been focusing on what Mrs May and Mr Juncker in a joint statement called"appropriate legal assurance to both sides".
Brexit Minister Steve Barclay will be back in Brussels on Thursday, along with the Attorney-General Geoffrey Cox.
Ever since Britain voted by 52-48 per cent to leave the EU in a referendum in June 2016, the political class has been debating how to leave the European project forged by France and Germany after the devastation of World War Two.
While the country is divided over EU membership, most agree it is at a crossroads and that its choices over Brexit will shape the prosperity of future generations.
Investors and many company chiefs are worried leaving without a deal will shatter Britain's reputation as a stable destination for investment and slowly weaken London's position as a global capital.
Some senior British ministers have warned Mrs May she must agree to delay Brexit if there is no divorce deal or face a rebellion in Parliament next week, the Sun newspaper reported.
When asked directly if Hammond would leave the government if May decided to leave without a deal, he said: "All I am going to say to you in I always do what I believe is in the best interest of the country." Asked if it was in the best interests of the country to go to a no deal, he said: "No definitely not."
