It’s been a busy and complicated visit to the USA for the Prince and Princess of Wales, as the pair arrived in Boston for the Earthshot Prize.

Prince William and Kate Middleton attended an NBA basketball game between the Boston Celtics and the Miami Heat, and helped kick off the annual Earthshot prize, which recognises contributions to environmentalism.

The awards ceremony is set to take place on December 2, and the royal couple have been exploring Boston and meeting its people while they’re in town.

It hasn’t been without issue, however, as a race row at Buckingham Palace has overshadowed much of the trip, and there were a number of ‘boos’ from the crowd as the couple appeared on the screen above the basketball game. It was also followed by a chant of “USA USA”.
