When I first heard that Buckingham Palace had decided to ban Nick Griffin from attending the garden party this afternoon, I thought "hmmm, bad move". However, having seen their reasoning I think they've done the right thing. Griffin had stupidly milked the invitation for party political purposes. If he had said nothing, attended, and then crowed about it, the Palace could have done nothing.
It shows what an amateur he is, in so many ways and the internal pressure on him to quit will become a little stronger as a result.
