The Secretary of State is warning Northern Ireland is on a path to further intervention from the UK Government - if things don't change.
James Brokenshire is due to address senior business leaders as part of a banquet at Queen's University in Belfast.
He'll urge Northern Ireland's 100 biggest firms to put pressure on the DUP and Sinn Fein to come together and form an executive.
In a keynote speech, Mr Brokenshire is expected to say: "I would encourage all of you here to continue to make it clear to the political parties just how important the restoration of devolved government is for business, for ordinary people and for Northern Ireland as a whole.
"We all want to see the parties come together and form an Executive. They need to hear from you just how important it is for to you to see them working together for the good of Northern Ireland.
"And deliver the bright positive future for NI we know we can achieve together."
