Didn't BNP leader Nick Griffin launch their manifesto in Swansea a few years back?
When he did, he had thoughts then of Swansea being the BNP's most fertile territory in Wales for support. Swansea's one of the biggest near-monocultural cities south of Middlesborough, so he may have had a sort of a idea going on somewhere in his 'thinking' ... I'm no defender of racism round here -- there's plenty of it in some places that I've been in the area, and when I encounter it, it pisses me off big style.
But bigger picture -- BNP support round here is in fact very limited. I believe the BNP have not even saved a deposit in the SA area.
