As opposition parties, and one Conservative MP, unite to take control of Parliament on 25 June, Labour’s Sir Keir Starmer set out the motion aiming to block a no-deal Brexit.
He said it would stop a future PM “foolish enough” to pursue no deal without the backing of MPs by proroguing – or shutting down – Parliament.
The shadow Brexit secretary described it as a “safety valve” in the Brexit process and reminding a future leader “this House will take every step necessary to prevent a no-deal.”
