Her Majesty the Queen was today praised for her amazing dedication and service to the country in front of a star-studded congregation at a special thanksgiving ceremony in London.
Prince William, Prince Harry and the Duchess of Cambridge led the throng of celebrity guests, high-profile politicians and dignitaries who turned out to help kick-off the three-day celebrations to mark the monarch's 90th birthday.
In a moving speech to more than 2,000 people who gathered inside St Paul's Cathedral, the Archbishop of Canterbury, Justin Welby, praised the way the Queen had ruled 'through war and hardship, through turmoil and change during the course of her 90 years' and asked the congregation to look back on her rule 'with deep wonder and profound gratitude'.
Others, including David Attenborough, also paid tribute to her long rule as smiled gracefully alongside her husband Prince Philip – who is celebrating his 95th birthday today – and gave fans a royal wave.
The special service, held at 11am, kicked-off a weekend of spectacular celebrations to mark Her Majesty's birthday, with several events across the capital planned including Trooping the Colour on Saturday and a parade down The Mall on Sunday.
However, despite the planned weekend of festivities, Prince Harry said today that the best birthday present his grandmother could receive would be a 'day off so she could lie about and do nothing'.
