The direction of travel in the argument for Britain’s future relationship with the EU is taking many twists and turns.

Last week MPs approved a non-binding motion saying the UK should stay in the customs union after Brexit, giving suggestion that Remainer MPs could win in crucial votes later this year.

But yesterday’s resignation of Home Secretary Amber Rudd- a key campaigner for remain in the referendum, has weakened the Remainer cause in the Cabinet.

Whoever takes up the role could determine the balance of power on Brexit at the heart of government as we edge closer to the start date of 29 March.
