Hopefully not, Fleurpepper.
From a purely political point of view, Sunak needs to be strong enough to tell his party that he will take this to a vote in Parliament. He needs to say that if it wins because of Tory votes, then everyone wins. If this happened he would gain power over the ERG.
He also needs to tell them (all Conservative MPs at a meeting of the 1922 Committee, perhaps) that if it wins, but needs the Labour votes to get it through, he will go to the country.
Unless Sunak stands up to the thugs in his party, this will fail once again.
