The big thing that BNP is, and what attracts increasing numbers of UK voters, is the only UK party which is unapologetically anti-Islamic-immigration.
The message being sent to the Conservative party is "you WILL stop being so PC, polite, and deferential towards the Muslims, or we will vote BNP".
“The big thing that BNP is, and what attracts increasing numbers of UK voters, is the only UK party which is unapologetically anti-Islamic-immigration.”
They are anti-all immigration. They also have plans to use taxpayer money to pay people to leave the country (because if your grandparents were one of the people who came from the West Indies to the UK in the 1950s then you’re not British).
But you’re correct that they have tended to focus on their anti-Islamic statements in recent years, (correctly I would have thought) making a judgement that there are more votes in that than their more traditional anti-semitism.
