For the very first time in her sixty-year reign, Britain’s Queen Elizabeth II sat in on a Cabinet meeting. The last time a reigning monarch has done so was in 1781 with King George III. Upon her arrival at 10 Downing Street, Prime Minister David Cameron welcomed the queen who posed for photographers. The prime minister escorted the queen to the Cabinet Room, where the weekly Cabinet meetings of government ministers takes place. While there, the queen sat between Cameron and William Hague, the British Foreign Secretary. Queen Elizabeth listened to her government discuss the military and political situation in Afghanistan. During her ninety minute visit, the queen was presented with an elaborately painted set of 60 placemats. Queen Elizabeth also visited the Foreign and Commonwealth Office. Foreign Secretary Hague announced that 169,000 square miles of the Antarctic was named “Queen Elizabeth Land” as a tribute to Her Majesty and her sixty-year reign. The territory, which had been unnamed is a third of the whole land mass of the British Antarctic Territory and almost twice the size of the United Kingdom. Photos by Getty Images.
