A key meeting of the British and Irish Council over Brexit is set to take place in Wales.
Northern Ireland's First Minister Arlene Foster and deputy First Minister Martin McGuinness will travel to Cardiff to take part in Friday’s talks with leaders from across the administrations.
The outcome of the historic referendum on the United Kingdom’s membership of the European Union is expected to dominate the discussions.
First Minister of Wales Carwyn Jones, who called the meeting, said it will provide an opportunity for national leaders to get together and look at the way forward.
He added: “The council plays a unique and important role in developing positive relationships between its members.
"During this tumultuous time, it is more important than ever to maintain the strength of this relationship and work together to map out a successful way forward."
Deputy First Minister Martin McGuinness says he has “no faith” that Parliament would vote to reject the Brexit process being triggered.
The Northern Ireland peace process is based upon membership of the European Union, the High Court has heard.
Ulster Unionist leader Mike Nesbitt warns Northern Ireland faces a 'decade of uncertainty' following the UK's decision to leave the EU.
