Senior Leave figures want the government to do much more to publicly prepare the public for a Brexit on WTO terms. Theresa May’s speech in January arguing that “no deal is better than a bad deal” pleased Tory Leavers, but they fear not enough has been done by Downing Street to prevent continuity Remainers seizing the narrative and convincing the public that WTO terms would be a disaster. This is why over the weekend Boris Johnson, David Davis and Liam Fox all came out and made encouraging noises about the possibility of no deal.

There are three reasons why Leavers want Number 10 to do more to make the WTO case. First, the chances of a Brexit along WTO lines are much higher than the government publicly admits. While the official line is that no deal is “unlikely“, behind the scenes senior figures in Number 10 have said they put the probability at around 30%. Most Leavers think this figure is optimistic. Another government source tells Guido they believe the likelihood of a WTO Brexit is 50-50.

Second, demonstrating that WTO terms are acceptable is vital for the negotiation. If Brussels believes Britain thinks WTO rules are a disaster, the threat to walk away is not credible. Going into the negotiation without being happy to accept WTO terms is obviously the worst possible negotiating hand. A Whitehall source says: “People are being told that WTO rules would be the end of the world. We need to explain to them why it isn’t”.

Third, Leavers want to learn the lesson from Cameron’s failure to make any contingency planning for Brexit. This is seen by the government as Cameron’s worst betrayal – Leavers are determined not to repeat the mistake. This means proper preparations for a WTO Brexit, both in terms of contingency planning in Whitehall and preparing the public for that outcome.
