Do you think that it possible to be so racist and extreme that you could be thrown out the BNP?

Answer 1

1. Yes, it is possible, and it does happen. However expulsions are kept fairly quiet, because they embarrass the party. The same thing happens when the Conservatives expel racists - it's an embarrassment to publicly admit that these people had been accepted as members.

2. Schisms can take place too. However, the far right usually splits over personalities, it is the far left that tends to split over ideology. Here's an excellent example of personality clash. In this article, the late John Tyndall, a far right activist since the early 1960s, criticises the current leader BNP Nick Griffin.

2. Over the years there have tended to be two political parties on the far right - a larger "respectable" party, and a smaller "extreme party" so there has always been an obvious home for the more fanatical far right activists.
a) In the 1930s these roles were played by The British Union of Fascists and the Imperial Fascist League

b) In the 1950s - The Union Movement, and a loose group of activists centred around Arnold Leese House.

c) In the 1970s - the National Front and the British Movement.

d) 1990s to present - the BNP and Combat 18.

3. The BNP tries to be respectable, so anyone publicly making "unacceptable" statements will be expelled. This happened to Sharon Ebanks, less than three months ago, after she made anti-Semitic remarks (that was the official reason).
