The Foreign Affairs Minister says relations between the British and Irish governments are now in 'uncharted waters'.
Simon Coveney says he has never seen relations like this before, as the row continues over the UK governments unilateral action to unpick parts of the Northern Ireland Protocol.
He says if the action is a negotiating tactic, then it's a pretty bad one as compromise becomes more difficult.
Minister Coveney has described the action taken by the British government as 'reckless':
Meanwhile, 52 of the Norths 90 MLA's have written to British Prime Minister Boris Johnson saying they reject his government's "new reckless protocol legislation".
But DUP Leader Jeffrey Donaldson said a letter from a majority of the North's MLA's is pointless.
"The institution in the assembly can only be restored on the basis of a cross-community consensus - majority rule will not cut it," he added.
"That is what the Unionists were told all these years, so to the Alliance, SDLP and Sinn Fein - who have written this letter without the support of Unionists - the political institutions cannot operate."
