The National Front are an ultra-right group native to the United Kingdom who have roots in Neo-Nazism and Facist (sic)philosophy, they believe in removing all non-Whites from Britain and are considered a hate group by most political parties, some of which have advocated banning them under new terrorism laws.
The National Front is often compared to the BNP - however the BNP broke away from the National Front some time ago and the BNP is denounced by the National Front as "going soft" (despite being seen as racist by most other parties).
