Prince Harry has announced a series of charity engagements in the UK and US this September, in what is being seen as a stepped-up public role amid ongoing tensions with the Royal Household. The move follows a letter of "guidance" issued on King Charles's behalf, which confirmed the Duke and Duchess of Sussex have not returned as working royals and cannot use their HRH titles, prompting Harry and Meghan's camp to hit back, arguing that describing them as "private citizens" is unrealistic given their fame.

Harry's UK engagements include the inaugural Invictus Spirit Awards, the launch of the Invictus education programme INSPIRE, and the WellChild Awards, before he travels to New York on 22 and 23 September to join Bill and Hillary Clinton, Chrissy Teigen and Reid Hoffman at the Clinton Global Initiative during UN General Assembly week. Sources close to the couple say they were "surprised" by the King's letter, sent with just over an hour's notice via the Lord Chamberlain, and prefer to be described as "public figures" rather than private citizens, amid a separate ongoing dispute over taxpayer-funded security and concerns for Archie and Lilibet's safety.
