John Bercow agrees that there is no way for parliament to block the UK leaving with no deal on October 31st 2019. Bercow told the French daily Le Figaro at the weekend: “Our default legal position, if no deal has been approved and if no extension is negotiated with the EU, is that we will leave the Union. In other words: we will be unable to prevent a hard Brexit. But if you ask me if there is a majority in parliament in favour of a no-deal exit, my answer is no.”
The only way to stop a committed leader from exiting the EU on WTO terms then, is to bring the Government down in a vote of no confidence in the hope that a Government committed to remaining, i.e. revoking Article 50 will be elected.
Anyone who states “no deal will be blocked” is simply ignorant or peddling second rate propaganda that fools no-one.
