An extended military flypast will take place following the King's first birthday parade after the display on coronation day had to be scaled down due to bad weather.
Around 70 aircraft from the Royal Navy, British Army and Royal Air Force will take part in a flypast for Trooping the Colour on Saturday, marking the first birthday flypast for Charles.
The King, Queen and other members of the royal family are expected to watch as the aircraft fly over The Mall and Buckingham Palace in a six-minute display.
