“We have been consistent that we will only ever consider supporting arrangements that are in Northern Ireland’s long-term economic and constitutional interests and protect the integrity of the Union. These proposals are not, in our view, beneficial to the economic well-being of Northern Ireland and they undermine the integrity of the Union,” Northern Ireland’s DUP said in a statement.
It comes after the deal was announced on Twitter by Juncker, who said it “focused on the protocol on Ireland/Northern Ireland and sought to identify a mutually satisfactory solution to address the specific circumstances on the island of Ireland.”
The question of the Irish border has been a major sticking point in the long negotiations and while both Johnson and the EU have agreed to the new terms, the Prime Minister’s next challenge will be getting his deal approved in the UK Parliament.
Former Prime Minister Theresa May also secured a deal with the EU, but failed to pass it through the House of Commons on three occasions.
The EU’s chief negotiator, Michel Barnier, said in a news conference in Brussels that the new text provides “legal certainty in every area where Brexit like any separation creates uncertainty.”
He said Northern Ireland will remain aligned to a “limited” set of EU rules related to goods, that it will remain in the UK’s customs territory — but also the entry point into the EU’s single market — and the Northern Ireland assembly will be given a vote on whether to continue to apply EU rules in the region or not every four years.
Barnier added that the proposal also covers the transition period, which will run until the end of 2020 — with the possibility to extend.
Johnson tweeted shortly after obtaining the agreement with the EU that now that Northern Ireland will remain part of the UK’s customs territory, it means the “anti-democratic backstop has been abolished.”
The backstop was an insurance policy designed to avoid a so-called “hard border” between Ireland and Northern Ireland if no other solution was found by the end of the transition period in 2022. It envisaged that the whole of the UK would remain tied to the EU’s customs union until a trade deal was concluded between the two sides.
UK opposition parties reject Johnson’s deal
After the announcement, the UK’s two main opposition parties also said they would reject the Brexit deal — putting another spanner in the works for the Prime Minister.
Labour’s Jeremy Corbyn, who leads the biggest opposition group in the House of Commons, said in a statement that Johnson’s agreement was worse than what was previously agreed by May.
“From what we know, it seems the Prime Minister has negotiated an even worse deal than Theresa May’s, which was overwhelmingly rejected,” Corbyn said.
“This sell-out deal won’t bring the country together and should be rejected. The best way to get Brexit sorted is to give the people the final say in a public vote.”
Meanwhile, the Scottish National Party (SNP) — which is the second-biggest opposition party in the UK — also said it would reject Johnson’s deal because it did not allow Scots any say over whether it should be implemented.
The nation overwhelmingly voted to remain in the European Union in the 2016 Brexit referendum.
The Liberal Democrats, which also does not support Brexit and wants to stop it from happening altogether, have also opposed the deal.
The series of rejections means in order for Johnson to get the deal approved by Parliament, he’ll need the support of all of his Conservative MPs, plus the 21 lawmakers he expelled after they defied him in an effort to prevent a no-deal Brexit, plus some members of the opposition.
Most estimates suggest that there are between five and 20 Labour MPs who might support a Brexit deal in defiance of their leader — making things very tight for Johnson.
If the Prime Minister can’t get parliamentary support for his plan by Saturday, he is legally obliged to write to the EU requesting a Brexit extension until January 31, 2020. He has until October 31 — just 14 days — until Britain is due to exit the bloc.
However Juncker on Thursday ruled out an extension to Article 50. “We have concluded the deal and so there is not an argument for further delay. It has to be done now,” he said.
