Strange how politics changes tho.
I remember during the That cher years, the Labour party was "finished" - then 1997 happened, and guess what, the Tories were "finished"
It't not that long since the last EU elections, which was the "ned of the Tory party". meanwhile Labour were going to be in hock to Momentum, the McDonnells, and the Milnes and the Murrays and the Murphy for decades culminatiing in some sort of Soviet state if they ever got their way.
Now Starmer is quietly purging Labour of that, the Tories far from dying have an 80-seat majority and despite all the talk of a new politics, with multiple parties, we are back to two main parties again.
So it might be foolish to predict anything much.
