I watched it all on YouTube, as the BBC blocks all access to its programmes here in the States.
I really had no idea who most of these folks are, but Nick Griffin seems to do a lot of back-pedaling. I'd bet if he were surrounded by his "troupe", he'd be spouting his racist rhetoric much more confidently. He appeared to be assuming the position of being victimized in newspaper and news headlines, and not at all culpable of his own actions.
As an American, I don't know much about British politics, and I surely wouldn't presume to give much of my own two pence about it, but as a side note, I really enjoyed trying to guess the locality of the accents of the people in the audience!
