A heavily pregnant Kate Middleton has arrived at Westminster Abbey with Prince William for a service celebrating the 60th anniversary of the Queen's coronation.
Within the ancient walls of Westminister Abbey, her Majesty will remember the day she was crowned on June 2, 1953, marking the milestone with the nation and her family.
Kate wore the Jane Taylor hat she wore to the jubilee and an elegant nude dress and matching coat from British designer Jenny Packham, one of the Duchess's favourite labels.
