Parties stand together as they tell PM that his plan for EU withdrawal is unacceptable

MLAS have rejected the Government’s EU withdrawal plan, with members reaching an agreed position without dissent following a near three-hour debate.

It was one of the first substantive acts of business since the Assembly was restored earlier this month.

The DUP and Sinn Fein are both strongly opposed to the Prime Minister’s Brexit deal — for different reasons.

Addressing the Assembly yesterday, Deputy First Minister Michelle O’Neill said: “We must work together with common cause to overcome the challenges that have been imposed on us by Brexit.

“This Assembly has not given its consent to the British Government to legislate on our behalf.”

The decision by MLAs will not affect the Government’s plan to leave the EU at the end of the month.

Northern Ireland voted in favour of Remain in the 2016 EU referendum, but there was a significant body of mainly-unionist opinion in favour of Leave.

The DUP opposes Mr Johnson’s plan over fears it could impose customs checks on goods travelling between England, Scotland or Wales and Northern

Ireland. First Minister Arlene Foster urged the Prime Minister to “deliver on his promise” of unfettered access to the Great Britain market and ensure that “competitiveness is maintained”.

She said the Brexit deal posed “significant challenges for Northern Ireland” and called on Assembly members to “take a stand” to show that it was “back in business” and will not be overruled by the Government.

Nationalists and businesses are keen to ensure the Irish land border remains open and frictionless, and are mostly in favour of remaining within the EU bloc.

There have been fears leaving could encourage dissident republican violence or reopen the debate over Irish unity, since the Republic of Ireland remains a member state.

Ms O’Neill said an EU pledge which would see Northern Ireland regain EU membership in the event of unification was a key factor.

“That has changed the context of the conversation and I think there is a very positive conversation under way now which is irreversible, I think that’s where the whole political debate is,” she said.

SDLP leader Colum Eastwood attacked the Government’s record on Brexit.

He said: “They do not care about people here, they don’t care about people in Scotland, and they are determined to go on with the madness that is this Brexit.

“Next week we will be dragged out of the European Union against our will, against the will of people here and people in Scotland. That’s why it’s important that we’re here, that’s why it’s important that we’re rejecting it.”

Alliance Party MLA Kellie Armstrong said there is no such thing as a good or sensible Brexit, but, accepting that it will happen at the end of the month, she added that it is time to “stand up and protect Northern Ireland”.
