UK has now got even more of Nigel Farage !

Tories and Reform are not really, matey, and the same thing.
Differ a lot on what they would do legislatively.

Its perhaps their fault that they can't join together.
Or Reformers can't just strategically vote Tory where Labour is stronger.
Much of Tory failure in Government maybe internal fragmentation within their own team too.

Tories have probably benefitted enough from FPP to not be enthusiastic.
Even if Nigel is a convert.
( Though similar voices have in past been 'very caustic' on how long it can take to form Governments ) 

Labour and other Left parties would ideologically favor proportional.
Then there is can-of-worms on what kind of proportional.

So I suppose it requires a definite cross party move.
