The new Shadow Secretary of State Hilary Benn will meet the five main Northern Ireland parties at Stormont later.
Mr Benn is on his first trip to Northern Ireland since his appointment a month ago.
The son of former cabinet minister and veteran left-winger Tony Benn, he has represented Leeds Central in the House of Commons since 1999.
He served in the last Labour cabinet from 2003 to 2010.
More recently, he has been shadow foreign secretary and chairman of the Brexit select committee.
