MARIE Rimmer MP has revealed she will not be supporting Boris Johnson’s Brexit deal in a crunch vote on Saturday.

Sitting for the first time in the House of Commons on a Saturday since the Falklands War, MPs will vote on whether to back the Prime Minister’s withdrawal agreement.

The European Council have already endorsed the deal but it is now up to MPs in the UK to pass the deal through Parliament.

Mr Johnson said he is “very confident” MPs will back the deal, despite the DUP maintaining it cannot support it as it stands.

Opposition parties are also expected to vote down the withdrawal agreement, making the possibility of it passing slim.

St Helens South and Whiston MP Marie Rimmer believes the new withdrawal agreement is worse than the previous Prime Minister Theresa May’s deal, which was voted down by MPs on three occasions.

The former leader of St Helens Council said she will cannot back the deal and believes it should be put to the people in a confirmatory referendum.

“It is clear that Johnson’s deal is a far worse deal than Theresa May’s deal,” Ms Rimmer said.

“It paves the way for a decade of deregulation. It threatens jobs, workers’ rights, environmental standards and consumer protection.

“It rules out a new customs union and close working relationship with Europe.

“The Chancellor Sajid Javid has refused to provide a financial impact assessment. With a decision as significant as this one it should be automatically released.

“Labour and I cannot support this deal.

“The Prime Minister should put this back to a People’s Vote, and I shall be supporting that call.”

MPs will convene in the Commons at 9.30am with a statement from the Prime Minister, followed by questions.

A number of amendments to the actual motion on the Brexit deal will be selected for a vote by the Speaker, John Bercow.

If the deal on the crucial vote is lost, then the Benn Act, a new law passed by MPs last month, will come into force.

This will require the Prime Minister to request a fresh extension from the EU in an attempt to avoid a no-deal Brexit.
