Queen Elizabeth II hosts a garden party in the gardens of Buckingham Palace on July 22, 2010 in London, England. At least three garden parties are hosted by the Queen every summer, an event which dates back to the 1960's and are held as a way of rewarding and recognising public services. British National Party leader and member of the European Parliament Nick Griffin who had initially been invited to attend the event has had his invitation revoked after officials said he was using his invitation for party political purposes.
