Sir Keir Starmer will meet the first and deputy first ministers at Stormont later as part of his first visit to Northern Ireland as prime minister.
The Labour leader is on a tour of the UK after becoming prime minister on Friday and visiting Scotland on Sunday.
He will also meet with representatives from the Executive and opposition parties.
Ahead of the meetings, Sir Keir said “stability and certainty” would be at the centre of what his government does for Northern Ireland.
“We are the party of the Good Friday Agreement, and the stability it has brought,” he said.
“Together, as we take the steps towards a decade of national renewal, we will harness Northern Ireland’s vast economic strengths – rebuilding strong public services and generating real and tangible economic growth for working people.
“We must turn the page and secure investment, prosperity, and stability for future generations to come.”
