Ireland’s premier has said the EU’s chief Brexit negotiator has demonstrated his “desire to be solution-driven” when it comes to the Northern Ireland Protocol.

Taoiseach Micheal Martin made his remarks on Monday in response to Maros Sefcovic’s suggestion that physical checks on goods travelling across the Irish Sea could be cut to a “couple of lorries a day”.

Mr Sefcovic told the Financial Times that Brussels stands ready to work in an “open and constructive” way with Britain following a statement from new Prime Minister Liz Truss on the prospect of a negotiated settlement on the protocol.

He argued that the trade border would be “invisible” under the EU’s plans, with goods processed “remotely” while making their way to Northern Ireland, as long as the UK provides real-time data on their movements.

It comes as the UK and EU have been embroiled in a row over Britain’s proposals to override parts of the controversial post-Brexit treaty, as it seeks to reduce trade barriers with the region.

Speaking at Fianna Fail’s parliamentary think-in in Mullingar in County Westmeath, Mr Martin said: “What Maros Sefcovic is demonstrating is his flexibility, his desire to be solution-driven, and what you’re witnessing this morning is further solutions, proposed ideas around resolving the protocol issue.

“I spoke with the British PM late last week. It was a preliminary discussion. We will meet again on these issues.

“I do believe genuinely there’s a view … that we should do everything we can to resolve this issue.”

He added that the “European Union and the UK really should sort this out so that we can focus on the bigger issues geopolitically that are facing the European Union and UK, who are good partners on these more fundamental issues.”

On Wednesday, Ms Truss said her preference is for a negotiated solution to the dispute.

But she said such a resolution would have to deliver “all of the things we set out” in the Northern Ireland Protocol Bill, which is currently making its way through Parliament.

The legislation would allow ministers to unilaterally scrap the arrangements the UK signed up to as part of the Brexit Withdrawal Agreement.
