I don't think they should even consider themselves eligible to have any parliamentary representation, even assuming they can get a significantly larger proportion of the popular vote ( I might be wrong, but I think the best they achieved in any one seat was around 2%), until they resolve the legal battle over the high court imposed injunction regarding their discriminatory membership policy and constitution.
And they probably need to sort out a senior membership that either gets arrested for issuing death threats against the party leader (Mark Collett, April2010), or arrested over a televised street scuffle ( Bob Bailey, May2010) , or a webmaster who resigns and closes the BNPs official internet web pages, twitter and facebook accounts (Simon Bennett, May2010). They might want to consider why they cannot hang onto their local councillors. ( Mark Logan Apr2010, "BNP too racist", Alby Walker Apr2010 " Nasty anti-semitic strain running through the BNP"). Oh yes, and losing all 12 local councillors in Barking and Havering - to Labour.
