Hundreds of royal fans have gathered around Windsor Castle to celebrate Queen Elizabeth II's 90th birthday. She celebrated her birthday by greeting well-wishers (many of whom have camped overnight to see her, in what they have called 'Queen's 90th Birthday Walkabout') near her Windsor Castle home. The Queen will end her 90th birthday by lighting a beacon, the first of around 1,000 to be lit across the country to mark the occasion.

Born on 21 April 1926 in Mayfair, Elizabeth II is still honoured to meet her subjects, and two surveys last week suggested the public do not want her to stop.

Birthday celebrations will pick up again in May, when there will be a four-day event at Home Park Private, Windsor Castle, where members of the royal family will attend each night. In June there will be further events to mark her official birthday, including the Patron's Lunch, a street party for 10,000 guests on the Mall.
