Sinn Fein has welcomed the European Union's draft proposal of a "common regulatory area" between the EU and Northern Ireland after Brexit but warned "the Tory-DUP wrecking-agenda cannot prevail".
DUP leader Arlene Foster and Prime Minister Theresa May have rejected the EU proposal, published on Wednesday morning, which would effectively see Northern Ireland remain in the single market and customs union after Brexit.
Speaking during Leaders' Question at the Dail, Sinn Fein president Mary Lou McDonald called the DUP and UK government "arrogant" for their reaction to the proposals in the draft agreement.
"The British Government and the Brexiteers engaged in the Brexit debate with zero regard for the impact on Ireland," she said.
“No concern for our economy. No concern for the rights of our people. No concern for the peace process.
“Now they want to conclude their debate, and make their exit, by putting the Good Friday Agreement through the shredder. The Tory-DUP axis is satisfied to treat the welfare of the people of this island as collateral damage so long as they achieve their ‘little Englander’ vision for Brexit.
“Their arrogance is best highlighted by their rejection to the vote by the people of the north to remain in European Union and most recently crystallised by Boris Johnson’s juvenile and dangerous commentary.
“The DUP has hitched itself to the Tory wagon. They have put narrow political interests ahead of the good of the people of the north from all communities, ahead of our economic well-being and ahead of the political process.
“The position of the Tory-DUP Brexiteers is that they will have their Brexit at any cost. Except it won’t be them who foots the bill. It will be the ordinary people of this island both north and south.
“That can’t be allowed to happen. The Tory-DUP wrecking-agenda cannot prevail."
Sinn Fein Vice President, Michelle O'Neill, also slammed the British Prime Minister and the DUP for their rejection of the EU Brexit proposals.
She said: “The Tories and DUP have no right to hold 27 EU nations to ransom. They have no right to play fast and loose with an internationally-binding treaty such as the Good Friday Agreement.
“It is also completely erroneous for Thesesa May to claim no British Prime Minister could agree to a proposal which she claims undermines her country’s ‘constitutional integrity’, when she herself agreed to it in December before her infamous phone call from Arlene Foster.
“The fact is that the British Government is continuing to pander to the most right-wing elements in her own party and the DUP.
“The other EU nations, and particularly the Dublin Government need to continue to stand firm in the face of that agenda and make it clear that we will not allow our future to be sacrificed on the altar of Tory-DUP arrogance and extremism.”
