The couple also greeted crowds from the balcony of the Town Hall, and are due to open the new £237m Alder Hey Children's Hospital. Queen Elizabeth changed out of her pink ensemble and into a floral dress for lunch, in another display of fashion daring as she seemingly shuns her usually-favoured matching ensembles for something a bit different. And judging by the smile on her face, she's enjoying trying something new!

Pictures of the Queen - making the cover of Vanity Fair in 2016

To mark her 90th birthday in 2016, the Queen graced the cover of Vanity Fair magazine for the second time after she sat for a series of portraits, shot by photographer Annie Leibovitz. Annie also photographed her birthday portraits (featuring other members of the royal family) but two of these images were exclusive to Vanity Fair. The cover image sees the Queen alongside her beloved corgis: Holly, Willow, Vulcan and Candy, and she is also pictured inside the magazine with husband Prince Philip in the Oak Sitting Room at Windsor Castle. Speaking of the photoshoot, Leibovitz told Vanity Fair: "The most moving, important thing about this shoot is that these were all her ideas. She wanted to be photographed with her grandchildren and great-grandchildren; her husband, Prince Philip; her daughter, Anne, the Princess Royal; and her corgis. I was told how relaxed she was at Windsor, and it was really true. You get the sense of how at peace she was with herself, and very much enthralled with her family." This photoshoot came after the Duchess of Cambridge was shot for the front cover of Vogue's centenary issue.

Queen Elizabeth was pictured at the National Memorial Arboretum in Staffordshire as she attended a serice for soldiers killed while serving in the Duke of Lancaster's Regiment. And despite her usual composed appearance, it seems that the emotions of the day became too much, as she discreetly wiped away her tear before closing her eyes for a few moments. She then laid a wreath with the message: 'In memory of the glorious dead. Elizabeth R.' The monarch isn't usually seen displaying emotion in public, but has been seen to do so, most usually at war memorials.
