The DUP says there’ll be consequences after accusing the Prime Minister of breaking promises over Brexit

The DUP says there’ll be consequences after accusing the Prime Minister of breaking promises over Brexit. But is the party bluffing? Will they really pull the rug from under Theresa May’s feet?

The party reacted angrily to a letter from Theresa May to DUP leader Arlene Foster, saying it "raises alarm bells for those who value the integrity of our precious union & for those who want a proper Brexit for the whole UK".

In the letter, leaked to the Times newspaper, Mrs May explains the EU wants a contingency of Northern Ireland staying in a customs union if no border solution is found during the post-Brexit transition period.
