Most duties can't be passed on to other family members while Her Majesty is Queen. However, she has been sending her children to represent her on royal tours for decades, and in her Diamond Jubilee year, they were all dispatched to the corners of the Commonwealth, as well as her two grandsons — William and Harry — for the first time, who visited Canada and some of the Caribbean islands respectively. Prince Charles has represented his mother at the heads of Commonwealth meeting, and has accompanied her to the State Opening of Parliament. He has been carrying out investitures (where titles are bestowed) for decades, and in 2013, Prince William performed his first investiture.
