Rebel MPs are working on a plan to thwart Boris Johnson pursuing a no-deal Brexit on 31 October that involves forcing parliament to sit through the autumn recess, amid growing outrage about the power and influence of his controversial aide, Dominic Cummings.

The cross-party group of MPs is looking at legislative options with mounting urgency because of the hardline tactics of Cummings, who one Conservative insider described as running a “reign of terror” in No 10 aimed at achieving Brexit on 31 October at any cost.
