The Minister for Foreign Affairs Simon Coveney has told Britain's Foreign Secretary that proposed legislation to change to Northern Ireland Protocol will create a whole new set of uncertainties and damage relationships.
The British government is due to publish details of proposed legislation to give ministers the power to override parts of the protocol.
The Irish Government and European Union have warned against unilateral action and urged a return to the negotiating table, but those pleas are set to be ignored.
Mr Coveney said it marks a particular low point in the UK’s approach to Brexit.
He spoke to Ms Truss by phone this morning, where she outlined her intention to publish the legislation today.
Mr Coveney said publishing legislation that would breach the UK's commitments under international law, the Brexit Withdrawal Agreement and Northern Ireland Protocol is deeply damaging to relationships on these islands and between the UK and EU.
