LONDON (Reuters) – Northern Ireland’s Democratic Unionist Party will not support Prime Minister Boris Johnson’s Brexit deal if he has to make more concessions to the European Union to get it done, the HuffPost reported on Tuesday.

“The problem is that the EU and Republic of Ireland see it as a chance to push for more,” the website quoted a DUP source as saying. “We will not be going more or giving more.

“Difficult times ahead.”
