This year was a biggie — on the day the queen turned 90, her presents included a chocolate model of Buckingham Palace from Cadbury, and her name written on a corgi hair by scientists from the University of Nottingham. Her Majesty went on a walkabout through Windsor and received a birthday cake from Great British Bake Off winner Nadiya Hussain. In the evening, Prince Charles hosted a sumptuous black tie dinner of salmon, beef in port, and tropical fruit gateau at Windsor Castle that was attended by William, Kate and Harry.
