To keep the party together. The reality is that the Tories have always been split but that split is deepening and widening. Cameron only saw off a shift to UKIP due to FPTP and Johnson did a dodgy deal with Farage but Reform UK are, again, a threat to the Tories always having the right wing vote with no splits. If Sunak can't keep the party together and Reform gain traction, or even get a few defections, the Tories are potentially condemned to grim future. Now, this is good for you and I but a disaster for "the party". And that's all this is for, appeasing the fascist wing of the party, keeping the evil, nasty, kill the country for a few quid more, professional bastard wing. I wish every single MP who voted for this a miserable life and a painful death.
