Queen Elizabeth's 90th Birthday Marked at Trooping the Colour Parade

 Dressed in a vivid lime green coat and matching hat, the Queen was escorted down the Mall in a horse-drawn carriage to the ceremony at Horse Guards Parade on the her official 90th birthday.
She celebrates two birthdays every year - her actual birthday on 21 April, and her official birthday held on a Saturday in June - in a tradition going back 250 years to try to ensure better weather for the monarch's official celebrations.
On Friday a national service of thanksgiving was held at St Paul's Cathedral paying tribute to the Queen's "faithful devotion" to the country.

 Archbishop of Canterbury Justin Welby said the Queen had reigned through "war and hardship, turmoil and change".

After the parade of more than 1,600 soldiers and 300 horses which held on Saturday, she appeared on the balcony of Buckingham Palace with members of her family, including Princess Charlotte, for an RAF flypast.

Visible in her vibrant ensemble, the Queen smiled and waved to crowds as she was driven with the Duke of Edinburgh in an open-top carriage up the flag-lined Mall.
She has attended the annual event - also known as the Queen's birthday parade - every year of her reign, except in 1955 when it was cancelled due to a rail strike.

 The Duchesses of Cornwall and Cambridge, both dressed in white, travelled together in another carriage with Prince Harry.
The Queen herself rode on horseback in the parade until she was in her 70s, riding side-saddle and wearing the uniform of the regiment whose Colour - or flag - was being trooped.
This year the Colour being trooped belonged to 7 Company Coldstream Guards.
