I took a few moments to look into it. Here's a few gems:
Voluntary re-patriation of all 1st and 2nd generation immigrants. Those choosing to go back to the land of their fathers will be handsomely rewarded with money that the current Treasury has earmarked for humanitarian aid for third world countries.
Free healthcare for OAPs.
Chemical castration for pederasts.
A ban on GM foods/crops.
National Service.
Capital Punishment.
All those completing service will be issued with a loaded gun which they may keep at home.
Withdrawal from the EU, and essentially existing as an isolationist, protectionist state.

Free healthcare for OAPs sounds reasonable
Yay - I'm voting BNP. Hang on...

Don't they have that already anyway?
Sounds like the BNP's policies from the 1950s to me.

Sources?
I'm looking at the BNP website right now... can't find all those... but they do want to abolish income tax, which is rather odd.
