(FILES) In this file photo taken on May 20, 2019 Britain's Catherine, Duchess of Cambridge (R) shows Britain's Queen Elizabeth II (L) and Britain's Prince William, Duke of Cambridge, around the 'Back to Nature Garden' garden, that she designed along with Andree Davies and Adam White, during their visit to the 2019 RHS Chelsea Flower Show in London. - William and Kate have brought a more relaxed and personal approach to royal duties and are raising their children in relatively hands-on fashion, presenting a more modern vision of the monarchy for a new age. The well-liked couple, formally known as the Duke and Duchess of Cambridge, married in 2011 and have presented themselves and their three children -- George, Charlotte and Louis -- as a model family.
