Got to be 1) no time for anything properly worked out, reluctant to make any long term decisions until there’s some planning done. I’m more hopeful if this Preston lad is six months than a longer contract TBH.
It’s not even the party. We elect MPs, they decide who they will follow. Nothing stopping a bunch of Tories getting together and following Jeremy Corbyn if that’s what they want (good luck keeping their membership/whip tho)
It’s a fundamental rewrite of the way we do government though. We don’t have a President, we have a Parliament and anyone who can command a majority in that parliament is the Prime Minister.
