Prince Harry Declined Invite to Duke of Westminster’s Wedding: ‘Understanding Between Two Friends’ (Exclusive)
The Duke of Sussex sends “his love and support and admiration for the couple” on their upcoming nuptials, a source tells PEOPLE

PEOPLE confirms that the Duke of Sussex, 39, was invited to the upcoming wedding of Hugh Grosvenor, the Duke of Westminster, to Olivia Henson at Chester Cathedral in northern England on June 7. However, there was an acknowledgment on both sides that it would be difficult for Harry to attend. Meanwhile, Prince William is expected to serve as an usher at what is regarded as the society wedding of the year.

Transatlantic travel to the U.K. is fraught for Harry due to security challenges in his home country. His official support was removed after he and his wife, Meghan Markle, stepped back from their royal roles and relocated to her home state of California in 2020. The Duke and Duchess of Sussex can also no longer use Frogmore Cottage, their former home in Windsor Great Park, as a base during stays in the U.K.
