When Buckingham Palace confirmed that the Sussex family had spent time at Highgrove House with the King on 10th July they included an important detail - Queen Camilla was there. Her relationship with her younger stepson hasn't always been smooth-sailing and some people might've been surprised that she was at the reunion.
According to royal author Catherine Mayer the Queen had to be there, because she's a "non-negotiable part of Charles' life". Opening up to People, she claimed if Harry wants to heal his relationship with his dad, Camilla is key as "there is no reconciliation with him without her."
