Possible conspiracy against the BNP

In the last few days I realised something which I can see happening. On one of his radio shows, Hal turner said that Nick Griffin (leader of the BNP) will be coming to the American Renaissance Conference this Saturday in America.

Is this a wise choice with him facing a retrial? Don't we have laws in this country which would mean he would be arrested for trying to flee the country while on bail? Nick might not have realised this but I think the government has. On the day that he gets on his plane (probably tomorrow) we could see him being arrested. The media will then make a big thing of it and then the government will have won and it will put a larger dent in the reputation of the BNP.

Of course they could just let him go and it might not even be illegal but I wouldn't want him taking that chance.

How likely is it?
