LONDON: British Prime Minister Theresa May will try to persuade her divided Cabinet on Wednesday that they have a choice between backing a draft Brexit deal with the European Union or plunging the UK into political and economic uncertainty.
Mrs May called a special Cabinet meeting after negotiators from Britain and the EU broke a months-long logjam and reached agreement on divorce terms, including a plan to keep the border between Ireland and Northern Ireland open after Brexit.
Mrs May was meeting with ministers one-on-one Wednesday morning ahead of the cabinet meeting at 2pm (9pm Bangkok time) in a bid to build agreement and stave off potential resignations.
Pro-Brexit lawmakers in Mrs May's Conservative Party -- including some members of the Cabinet -- say the agreement will leave Britain tethered to the EU after it departs and unable to forge an independent trade policy.
Mrs May's supporters argue that the deal is the best on offer, and the alternatives are a chaotic "no-deal'' Brexit that would cause huge disruption to people and businesses or an election that could see the Conservative government replaced by the left-of-centre Labour Party.
Former Foreign Secretary William Hague warned "ardent Brexiteers'' that if they shoot down Mrs May's deal, it could lead to a change of government and a new referendum and "Brexit might never happen at all''.
Failure to secure cabinet backing will leave Mrs May's leadership in doubt and the Brexit process in chaos, with exit day just over four months away on March 29.
If the cabinet supports the deal, it needs approval from the EU at a summit in the next few weeks. Then Mrs May will need to win backing from Parliament, where pro-Brexit and pro-EU legislators alike are threatening to oppose it.
The main obstacle to a withdrawal agreement has long been how to ensure there are no customs posts or other checks along the border between the UK's Northern Ireland and EU member Ireland after Brexit. Britain and the EU agree that there must be no barriers that could disrupt businesses and residents on either side of the border and undermine Northern Ireland's hard-won peace process.
The proposed solution involves a common customs arrangement for the UK and the EU, to eliminate the need for border checks, with some provisions that are specific to Northern Ireland.
The solution is intended to be temporary, but pro-Brexit politicians in Britain fear it may become permanent, hampering Britain's ability to strike new trade deals around the world.
Former Foreign Secretary Boris Johnson, who supports a clean break from the bloc, said the agreement would make his favoured option, a loose Canada-style trade deal with the bloc, impossible. He tweeted: "Cabinet must live up to its responsibilities & stop this deal.''
Northern Ireland's Democratic Unionist Party, which props up Mrs May's minority government, said it would oppose any deal that leaves Northern Ireland subject to different rules to the rest of the UK after Brexit.
DUP chief whip Jeffrey Donaldson said the proposed deal threatens "the constitutional and economic integrity of the UK''.
"That is not something we can support,'' he told the BBC.
Mrs May also faces growing opposition from pro-EU lawmakers, who say her proposed Brexit deal is worse than the status quo and the British public should get a new vote on whether to leave or to stay.
