The two main parties policies have converged, so have the older smaller parties.
The only choices we have that are any different are Reform and The Green Party, and possibly Corbyn's new party that seems busy imploding right now. Of those, Reform has some nasty people in it, and is rapidly attracting the worst of the Conservative party (look at the defecting MPs), The Greens and Your Party have some fairly nuts people and ideas too (in different ways).
I think ordinary British people are pretty decent.

We have a much bigger economy than Russia.

People are also negative about their follow citizens. A lot of people believe the country is full of untrustowrthy "gammon". and back the government/establishment against the latter.
