Duke and Duchess of Cambridge say goodbye to New York
The Duke and Duchess of Cambridge are on their way back to the UK after an action-packed visit to the United States.
The pair attended a gala dinner for their former university, St Andrews, last night in New York.
The Duchess has told how she was moved after visiting the memorial to victims of the September 11 terrorist attacks during their visit.
William and Kate paid their respects to the victims by laying a bouquet of white roses - the state flower of New York - on a bronze panel lining one of the pools that was embossed with the names of the dead.
