This is a great story in the Daily Mail:
The BNP is removed from the official list of political parties after its vote collapsed by 99.7 per cent and it failed to pay £25 fee
I can say this is primarily due to the rise of UKIP (where you cannot even become a member of UKIP if you ever were a member of the British National Party, among other parties and groups) as a legitimate anti-EU libertarian-leaning sovereignty party.
So raise up a sweet tea in salute (The Brits might say, Hear! Hear!) of UKIP that has now driven the BNP out of British politics. I doubt the left will offer that toast. But I do!
