William and Harry at Princess Diana's statue unveiling in July
Harry returned to the UK last month for the statue unveiling of his late mother, Diana, Princess of Wales at Kensington Palace, with his older brother, Prince William.
While the Duke of Sussex made a surprise appearance at the WellChild Awards at Kew Gardens during his visit, it has not been confirmed whether he met up with his father during his time in the UK.
Charles has not addressed his relationship with his youngest son in public, although Harry made it clear in his interview with Oprah Winfrey in March that there is "a lot to work through".
The Sussexes now live in Montecito, Santa Barbara, after stepping back from royal duties in March 2020.
