The possibility of Kate Middleton meeting with Prince Harry is dependent on King Charles's request with her beloved daughter in law.
As Prince Harry prepares to return to the UK for a significant celebration next week, it remains uncertain whether he will have a reunion with his elder brother, Prince William, or with Princess Kate during his visit to his home country.
However, according to one expert, the Princess of Wales will only agree to meet her brother-in-law under specific conditions.
This visit marks Harry's return to commemorate 10 years of the Invictus Games, and it will be his first time back in the UK since Kate emotionally announced in a video message to the nation that she had been diagnosed with cancer and started preventive chemotherapy.
One expert isn't quite so sure that Kate will reunite with her brother-in-law at this stage, believing that the meeting will only occur on one condition. Ingrid Seward - Editor-in-Chief of Majesty Magazine - explains that in her view, it's "highly unlikely" that William will want to see his brother during this stressful period.
The royal expert said: "William has enough going on and doesn't need the stress. But he might realise Harry will want to see Kate after her cancer diagnosis as they were once so close.
"It remains to be seen if Kate is willing and able to face up to it. Does she have the energy to begin to try and heal the rift between the brothers or will she prefer to remain in the background?"
Ingrid added that if the request to meet Harry comes straight from the top, Kate would be likely to agree to a reunion with her once-close brother-in-law.
"If the King asks, she will do it, but Charles being the sensitive and understanding soul he is, would be unlikely to ask such a favour from his adored daughter-in-law. The time must be right, and it is not right now."
Both Charles and Kate were treated in the London Clinic at the same time earlier in the year, and it has been reported that the monarch "toddled" down the corridor to spend time with Kate after she had undergone major abdominal surgery.
Just a few hours before her shocking announcement, Kate and Charles are reported to have had an "emotional" lunch, which sources said "The King left his lunch feeling very emotional," and noting "he thinks of Catherine as his daughter."
