David Davis has, I write in The Sun this morning, warned the Brexit inner Cabinet that if Britain is under the backstop at the time of the next election then the Tories will suffer a 1997-style defeat.
The Brexit Secretary argued that this risk meant that the UK had to keep control of the backstop: it had to be able to choose when to end it. But Davis lost this argument with the Prime Minister.
However, Number 10 have assured Brexiteer Cabinet Ministers that the UK will be out from under the backstop by the time of the next election in 2022. I am told that Theresa May is hopeful that the new customs arrangement can be nailed down by the end of 2021 at the latest.
But this seems distinctly over optimistic. HMRC have already warned that it’ll take three to five years to implement new customs arrangements.
