Queen Elizabeth II and members of the royal family gathered on Buckingham Palaces balcony to watch a flypast by the RAF which included the Red Arrows, two Spitfires and four helicopters. Kate Middletons daughter, Princess Charlotte, who was on the balcony for the first time, appeared alarmed by the noise of the aircraft and covered her ears.

The Queen is celebrating her official landmark birthday over the next three days in a series of fun-filled festivities. Her coronation was on 2 June 1953, making the Queen the longest-serving monarch in British history. She has become a much-loved and respected figure across the globe.

Though she was born on 21 April, 1926, and has already reached her 90th birthday milestone, Her Royal Highness enjoys two birthdays a year, and the British weather is to blame.

Since 1748, the monarchs official birthday has been marked by a parade called Trooping the Colour – previously held on the king or queens actual birthday.

However, when King Edward VII – who reigned from 1901 to 1910 – was born on November 9, 1841, he celebrated officially in May or June because there was less chance of it being rainy or cold during the outdoor event.

Unfortunately for the Queen, London is expected to be hit by showers all weekend, in true British summer style. There will however be a silver lining to Saturdays rather grey clouds, because it will be mild at 21°C. Sunday will see temperatures of approximately 19°C with lighter showers.

IBTimes UK rounds up the Queens big birthday weekend including when and where to watch the televised celebrations; so get your Victoria sponge and pots of tea at the ready as the regal revelries get under way.
