Crowds celebrate Queen Elizabeth's 90th birthday walkabout
Queen Elizabeth greeted thousands of well-wishers from across Britain and beyond as she celebrated her 90th birthday on Thursday, demonstrating the world's oldest monarch's intent to keep doing the job she has performed for more than six decades.
Usually the queen's birthday passes with little ceremony but to mark Thursday's milestone a beaming Elizabeth, attired in a light green outfit, mingled with crowds during a lengthy walkabout near her Windsor Castle home, west of London.
In a rare move in recent years, she then drove through Windsor in an open-topped car with Prince Philip, her husband of 68-years by her side.
Later the queen will light a beacon, the first of about 1,000 across Britain and worldwide to mark the occasion. There were also artillery gun salutes in London and other British cities, while the Houses of Parliament were to be illuminated later in red, white and blue.
