This stuff is just completely ahistorical.
We had the British Union or Facsists in the 1930s, the National Front in the 70S, BNP winning European Parliament seats 20 years ago....
All blamed the "establishment" for their racism and hate.
Britain doesn't have a 'far-right problem'. Britain has a problem with a dominant liberal class that for years ignored legitimate mainstream concerns over economic injustice, crime and immigration, and is now experiencing the blowback.
