One of these groups (the BNP) is an official UK political party and there are local elections next month, with postal ballets already been sent out. The party is pretty much dead now and has no parliamentary MPs and no existing local councillors (last one left last year), but there has been up to 59 councillors elected in the last decade, and it's unknown how many town and parish councillors there are (if any). I don't know how many candidates are up for election in these current elections.
