Rishi Sunak is set to face an intense 90-minute grilling by a group of MPs.
The Prime Minister will appear before the Commons Liaison Committee at 1pm today.
The panel is made up of the chairs of all the House of Commons select committees.
The topics due to be covered are scrutiny of strategic thinking in government, economy and public services, and global issues.
It comes as Mr Sunak is facing a fresh by-election challenge within weeks to replace an MP who lost the Tory whip after being caught in a lobbying sting.
