Theresa May’s Brexit deal is doomed – Sir Michael Fallon

Theresa May’s Brexit deal is “doomed” and must be renegotiated, ex-defence secretary Sir Michael Fallon has said.

Sir Michael launched a scathing attack on the proposed EU agreement, saying it was the “worst of all worlds” and the PM’s future was “up to colleagues”.

The prime minister is visiting Wales and Northern Ireland to argue her deal will bring certainty to business.

DUP leader Arlene Foster told BBC News the trip was a “waste of time” as Parliament would not support her deal.

Mrs Foster, whose party has a parliamentary pact with the Conservatives to support the government, said Mrs May had “given up” on trying to secure a better deal for Northern Ireland.

While people were “fed up” with the Brexit process dragging on, that was not a good enough reason “to accept what’s on the table”, she told the BBC’s political editor, Laura Kuenssberg.

Parliament will vote on whether to accept or reject the terms of the UK’s withdrawal and future relations negotiated by Mrs May on 11 December.

Sir Michael’s decision to come out against the deal is a blow to the prime minister, who is struggling to muster support in Parliament for it.

Labour, the Lib Dems, the SNP and the Democratic Unionists have said they will vote against the deal while many Tories have said publicly they are opposed.

Opponents of the deal say it will keep the UK too closely tied to EU rules and make it harder to strike future trade deals with other countries and minimise their value.

US President Donald Trump has suggested the withdrawal agreement “sounds like a great deal for the EU” and might hamper a future trade deal with the UK but Mrs May said this was not the case.
