BNP leader Nick Griffin has been banned from entering a Buckingham Palace garden party, after there were claims that he had used his invitation for political reasons. A spokesman said that his behaviour had 'increased the security threat and potential discomfort' of other guests.

Mr. Griffin told supporters on the BNP website that the invitation was a 'symbolic breakthrough' and solicited questions for the Queen from BNP members. In an appearance on GMTV, Mr. Griffin said that he had failed to attend last year's garden party because of pressure applied on Richard Barnbrook, who had invited him as a guest, but in this case he had been given his own invitation.

He said that he was 'pretty sure' he wouldn't meet the Queen, but was happy to talk to her over sandwiches if they had a chance meeting.

In a statement, Buckingham Palace said: 'The decision to deny entry is not intended to show any disrespect to the democratic process by which the invitation was issued. However, we would apply the same rules to anyone who tried to blatantly politicise their attendance in this way'.

Mr. Griffin said he would not try to attend the event, telling the BBC that 'in the end, it's the Queens' house, she can decide who she wants and who she doesn't want'. He said 'nowhere in the book of rules given to all attendees does it say anything about not giving media interviews, and, of course, countless people have done precisely that in the past.

This decision is an attack on the media, and their right to report on important events of the day'. Mr. Griffin said that he represented more than one million UK citizens, and saw his exclusion from the garden party as an act of the 'Lib Con' coalition.

All UK Euro MPs were invited to the event. The BNP's other Member of European Parliament, Andrew Brons, can still attend the garden party. There will be 8,000 guests at the event, which is hosted by the Queen and will be attended by the Duke of York, the Duke and Duchess of Gloucester and the Duke of Kent.
