at the last election the tories purged all remainers from the party, and what we ended up with was a load of ukip mp's under the tory banner. This election should see most of them lose their seats, so perhaps proper tories will make a re-appearance at the 2029 election.
What i mean by this is that what Starmer has done is purge the labour party to his own image, and that will probably attract a few traditional tories into the labour party because they previously had no home, so what we will get in labour is some weird labour/tory hybrid, but it won't be the right wing ukip tories that are currently all over the tory party. To me, it's a good thing, but maybe that's just me
