there is no broad left-wing party is the issue. the greens are lukewarm socialists/socdems, the NIP is socialist but small and regionalist, the worker’s party is just galloway being a careerist, all the communist parties have issues with racism/homophobia/transphobia/revisionism and no MP could survive the media while running as a communist anyway etc.
I may be biased as an anarchist but socialist independents seem to be the way to go for britain, given that every attempt at a socialist party invariably is usurped from within or sabotaged in the media - it’s harder for the MSM to sabotage hundreds of independent candidates rather than a single bloc, and voters tend to like independents for whatever reason - perhaps as an alternative to the westminster duopoly regardless of politics
