Sunak facing threat of Tory rebellion over Northern Ireland protocol plans

PM is embarking on frantic weekend of diplomacy in attempt to break post-Brexit deadlock

Rishi Sunak faces the threat of a fresh Conservative rebellion as he sets off on a weekend of frantic diplomacy in an attempt to break the post-Brexit deadlock in Northern Ireland.

With some in his party fearing an intervention by Boris Johnson, the prime minister has been warned his proposed deal on the Northern Ireland protocol does not go far enough after talks with unionists in a Belfast hotel on Friday.
