Well yes, the Tories need a new party leader to rebuild their party after the next election. Before the election? The new leader will just be a sacrificial lamb that’ll probably be thrown out onto the slag heap (hopefully a nice soggy wet one) at the next election.
It’ll almost certainly not save them from being wiped out (and that’s from 6 months ago; if anything, things are even worse today) at the next election.
An overwhelming majority of people want an election now and changing leaders now in what will be seen as yet another undemocratic move (it isn’t; it’s just people like to think they’re voting for a particular PM when they’re just voting for their MP) is likely to make the Tories even more unpopular.
If I were Starmer, I’d launch a parliamentary vote of no confidence as soon as the replacement showed up in parliament :-
The people don’t want you.
– Me putting words in Starmer’s mouth.
We don’t want you.
The other parties here don’t want you.
And if they were honest, half of those on your side don’t want you either.
He’d lose of course, but the people will see it as an honest attempt at doing the right thing.
