Royal couple’s visit will focus on climate change and the early years before culminating in the Earthshot Prize award ceremony on Friday.

The Prince and Princess of Wales are expected to meet US President Joe Biden in Boston on Friday, The Telegraph understands.

The Royal couple land in the US later on Wednesday for a three-day visit designed to focus on their pet causes of climate change and the early years before culminating in a star-studded Earthshot Prize award ceremony on Friday evening.

It comes amid a Royal race row after a senior aide made “unacceptable and deeply regrettable” comments to a black domestic abuse campaigner at a Buckingham Palace reception.

The aide, who has not been formally identified, has stepped aside from her role and expressed “profound apologies” for the hurt caused by comments made to Ngozi Fulani, director of the London charity Sistah Space, at the event on Tuesday.

For the Prince and Princess, the timing could not be worse. Their last overseas tour, to the Caribbean, was marred by criticism of its “colonial overtones” and “tone deaf” imagery.
