Choir boy collapses just yards from Queen at the Cenotaph As national anthem was sung, the youngster collapsed at the Cenotaph He was a short distance away from where the Queen placed her wreath Queen was joined by servicemen, senior royals and party leaders A young choir boy collapsed at the Cenotaph yards from where the royal family were standing during the Remembrance Sunday commemoration in central London. As the national anthem was sung, medics rushed to treat the boy who was helped up and led away through the crowd. The Queen wore a long black coat and hat and carried a black handbag during the service, while the Duke of Edinburgh, who joined the Royal Navy in 1939, wore the uniform of an Admiral of the Fleet for the ceremony. Collapse: A young choir boy collapsed at the Cenotaph yards from where the royal family were standing during the Remembrance Sunday commemoration in central London As the national anthem was sung, medics rushed to treat the boy who was helped up and led away through the crowd The boy looked shaken as emergency services personnel led him away In June a page boy collapsed as the Queen delivered her speech to Parliament was revealed to be the 12-year-old heir to one of Scotland's most senior aristocratic titles. Charles Hope, Viscount Aithrie, fell to the ground as the Monarch was in the middle of her speech, prompting her to flinch, but continue reading it. A clearly concerned Prince Charles and his wife, the Duchess of Cornwall, instinctively reached out in shock to the boy, who was helped by other officials from Parliament and the Royal Household. Viscount Aithrie is a future Earl of Hopetoun and Marquess of Linlithgow. His magnificent ancestral seat is Hopetoun House near Edinburgh, one of Scotland's finest stately homes. Anniversary: This year's service comes 100 years after the outbreak of the First World War and 70 years after the D-Day landings Paying her respects: The Queen, dressed all in black except for a red poppy, was laid a wreath on the Cenotaph on behalf of the nation Eight minutes and 53 seconds into her address, just after Queen told those gathered the Government will work towards a "comprehensive nuclear agreement with Iran," a loud thud could be heard as the poor boy lurched forward and hit the ground. As the Queen jumped, her son and his wife instinctively turned and put their hands out as if to grab the young page who was dressed in a heavy red and gold brocaded coat with a lace jabot, satin knickerbockers and white stockings. He was carried out of the chamber by other liveried members of staff and the speech carried on without further incident. In June a page boy collapsed as the Queen delivered her speech to Parliament was revealed to be Charles Hope, Viscount Aithrie, the 12-year-old heir to one of Scotland's most senior aristocratic titles Pages of Honour carry the Queen's train on ceremonial occasions and hold office for two to three years between the ages of twelve and fifteen. The boys are selected from among the sons of Her Majesty's friends and her Household. The Queen was applauded today as she led millions of Britons in remembering the fallen on Remembrance Sunday. The monarch laid a wreath on the Cenotaph at the national service alongside senior Royals, veterans and the Prime Minister despite heightened police checks, just days after officers thwarted an alleged terror plot. The spontaneous smattering of applause, as she left Whitehall in central London, was a rare sound for a remembrance service usually characterised by respectful silence, and may have been in tribute to her fortitude at turning out to the service despite terror fears. Giving thanks: The three main party leaders Ed Miliband, Nick Clegg and David Cameron were among those at the ceremony today Forty-six high commissioners from Commonwealth countries each laid a wreath before the Irish ambassador to the UK, Dan Mulhall, left a floral tribute. It was the first time a diplomat from the Irish Republic has laid a laurel wreath at the London Cenotaph - the latest in a line of symbolic gestures by both the UK and Ireland aimed at putting their troubled history behind them. Some 200,000 Irish-born soldiers from north and south of the island served in the First World War, with around 50,000 losing their lives. Following the wreath-laying, the Bishop of London, the Right Reverend Richard Chartres, conducted a short service in his role as Dean of HM Chapels Royal.
