May offered her desperate reassurance at the start of a three-hour cabinet meeting, during which ministers discussed the "mechanism" for ensuring the backstop wouldn't be permanent.
Brexit Minister Dominic Raab, who shocked the Irish government recently by demanding Westminster reserve the right to end the customs alignment with Brussels should the issue prove intractable, told mainstream reporters stood outside 10 Downing Street after the meeting "thumbs up" — suggesting he may have been promised such a clause.
‘Review Mechanism'
The meeting was held after May raised the Irish backstop issue with Irish Taoiseach Leo Varadkar in an unscheduled phone call November 4. The Irish government said the pair discussed a "review mechanism" in which the backstop could be ended only by mutual consent — but Downing Street's summary of the call was somewhat different, making no mention of any"review mechanism".
Whatever the truth of the matter, May needs to secure the backing of the cabinet, the sole remaining sticking point in Brexit talks that need to be concluded by the end of November.
A backstop is believed necessary to ensure there's no reimposition of a hard border in Ireland in the event the UK and EU are unable to agree a long-term free trade deal after the end of the Brexit transition period in 2020.
It would involve some or all of the UK remaining in the customs union until concord is reached — but several cabinet members are concerned a backstop arrangemens could be exploited by Brussels to pressure the UK during free trade negotiations — and Britain could also effectively be left in a long-term limbo, still in the customs union without any say in decision-making, as a result.
For its part, the Democratic Unionist Party's chief whip Jeffrey Donaldson has warned it "looks like we're heading for no deal" via Twitter, a message in response to Irish deputy prime minister Simon Coveney who earlier insisted a backstop could only be feasible if it didn't come with a time limit or the ability to be ended by the UK.
DUP's leader Arlene Foster has concurred with Sir Jeffrey's line, telling local Northern Irish media a ‘no deal' Brexit is "the trajectory we're on".
