Official celebrations marking Queen Elizabeth's 90th birthday continue in London today.
The Queen and other members of the royal family gathered on the Buckingham Palace balcony to watch a flypast of Royal Air Force jets and planes from the Second World War.
Earlier, the Queen sat at ground level to oversee a military parade known as Trooping the Colour, featuring more than 1,500 soldiers and several hundred horses.
Grandson Prince William, his father Prince Charles and aunt Princess Anne rode horses during the parade, a tradition that originates from preparations for battle, when flags are carried or "trooped" down the rank for soldiers to see.
Following the ceremony, thousands of people lined the Mall near Buckingham Palace to pay their respects.
Next in the lineup was a river pageant on the Thames. The flotilla included the royal barge Gloriana, the historic launch Havengore and a group of Dunkirk little ships.

They moved downstream from Westminster Palace and along the way passed the London Eye, Shakespeare's Globe and the Tower of London.
As the vessels reached Tower Bridge, it lifted and the flotilla passed underneath, marking the end of the pageant.
On Sunday, the party will include the Patron's Lunch to honour the Queen for her support of several charities.
The festivities were scheduled to unfold over three days. They kicked off on Friday with a Thanksgiving Service at St. Paul's Cathedral.

Four carriages carried members of the royal family to the palace for Saturday's ceremonies.
Prince Philip and the Queen, who wore a bright green outfit, were in the last carriage.
The Queen actually turned 90 on April 21, but official celebrations are held in June, a long-standing tradition.
