Carrying the baby boy in a car seat, William and Kate smiled and waved to a crowd of well-wishers outside the hospital before driving off in a Land Rover. Kensington Palace said the baby was born at 6:01 a.m. (ET) and weighs 8 lbs 7oz. William was present for the birth at St. Mary's Hospital in west London where their other two children, George and Charlotte, were also born, it added. "The Queen, The Duke of Edinburgh, The Prince of Wales, The Duchess of Cornwall, Prince Harry and members of both families have been informed and are delighted with the news," Kensington Palace said. "Her Royal Highness and her child are both doing well." The new prince is Queen Elizabeth's sixth great-grandchild and fifth-in-line to the British throne behind siblings Prince George, 4, his two-year-old sister Princess Charlotte, their father William, and grandfather and heir Prince Charles. A 2013 change to the law means the boy will not supplant older sister Charlotte in the line of succession. "That would in fact be the first time that has ever happened," royal historian Huge Vickers said. However, William's younger brother Harry, who marries actress Meghan Markle next month, falls to sixth on the list. Kensington Palace said the name of the new royal would be announced in due course. Bookmakers had made Albert, Arthur, Jack and Fred the favorite names for a boy. By Reuters Share on Facebook Share on Twitter Comments Comments section is temporarily on hold. Here’s why.
