pbr Britain's Armed Forces fighting in Afghanistan were joined by Prince William earlier for a Remembrance Sunday service as the Queen led the nation in honouring the fallen.br ppbr At London's iconic Cenotaph war memorial the monarch was the first to lay a wreath to commemorate those servicemen and women killed in all conflicts since the First World War.br ppbr Thousands of miles away William, an RAF Search and Rescue helicopter pilot, joined the military congregation at Camp Bastion in Helmand Province for their event honouring Britain's war dead.br ppbr The second-in-line to the throne laid a floral tribute to those who made the ultimate sacrifice in all conflicts and also visited the base's state-of-the-art medical centre with Defence Secretary Liam Fox.br ppbr The on-going conflict in Afghanistan has meant Remembrance Sunday still remains a poignant event for many - the number of those who have died since the start of operations in the country in 2001 is now 343.br ppbr Stuart Gendall, from the Royal British Legion, said: "It's a wonderful gesture, the men and women out there will be bowled over. He will be talking to them as a serviceman to servicemen and women. This is a huge gesture of respect and fellowship."br ppbr At the first stroke of 11am by Big Ben the two minutes' silence began.br ppbr The Queen stood metres from the Cenotaph eyes fixed on the memorial while behind the sovereign stood her family in a line.br ppbr The royal men and women all dressed in military uniforms were the Duke of Edinburgh, Prince of Wales, Duke of York, Earl of Wessex, Princess Royal and Duke of Kent, and all stood unmoving as the seconds ticked by.br ppbr Close by was Prime Minister David Cameron, Liberal Democrat leader Nick Clegg, opposition leader Ed Miliband, leaders of other parties, High Commissioners from Commonwealth countries and defence chiefs.br ppbr The crowds who numbered in their thousands and contained many veterans also watched in silence.
