After Prince Charles was unexpectedly needed at the Saudi Arabian funeral of Prince Sultan bin Abdulaziz Al Saud, Kate stepped in for her father-in-law at a private dinner he was hosting at Clarence House in aid of In Kind Direct. While this was the first time the Duchess was unaccompanied at an event, her public engagement for the National Portrait Gallery in February of 2012 is widely considered her first official public appearance. Certainly, this was an excellent dry run.
