Rishi Sunak has seen off a backbench revolt by Tory hardliners opposed to his new deal with Brussels on post-Brexit trading arrangements for Northern Ireland.
Just 22 Conservative rebels, including former prime ministers Boris Johnson and Liz Truss, defied a three line whip to vote against regulations to implement a key plank of the Windsor Framework agreement.
The so-called Stormont brake, designed to give a veto over the imposition of new EU rules in Northern Ireland, was passed comfortably by 515 votes to 29, with Labour and other opposition parties backing it.
