William and Kate seek to end US trip on positive note after turbulent week

Prince's Earthshot prize ceremony will round off week in which royal family has again faced accusations of institutional racism

The Prince and Princess of Wales are due to end their three-day trip to Boston on a high note, having landed in the middle of a palace racism row and then been blindsided by a trailer for the Sussexes' documentary.

A meeting with the US president, Joe Biden, and a star-studded award ceremony for Prince William's environmental Earthshot prize, were scheduled to round off what could be described as a bumpy few days.
