Queen Elizabeth II hosted the first of this year’s summer garden parties at Bucking Palace on May 22, 2012 when some 8,000 guests attended one of the season’s most anticipated gatherings. Guests are invited in recognition of their public service. The queen looked sprightly in a light orange ensemble. She was accompanied by the Duke of Edinburgh and Duke of York in morning coat and top hat and the Princess Royal in pink. The day proved to be warm and sunny, a pleasant change from recent rains.
