Taoiseach Micheal Martin has said he detects a genuine wish from Liz Truss to resolve the impasse over the Northern Ireland Protocol.
Mr Martin said there was a need for the EU and UK to now enter a process to negotiate a settlement over the contentious post-Brexit trading arrangements.
Officials from London and Brussels are set to hold discussions on the outstanding issues following a call on Friday between Foreign Secretary James Cleverly and European Commission vice president Maros Sefcovic.
