The estranged royal claimed in a 2017 interview that his relatives would merely accept the "duties" when the time came if they had to, but wouldn't desire to be monarch.
The Duke of Sussex hinted about his forthcoming departure from life as a working royal within 'The Firm' in a chat with author Angela Levin, as they discussed the struggle he faced in finding a meaningful role, reports the Express.
He also claimed the monarchy would have to change after Queen Elizabeth II's death.
"We want to make sure the monarchy lasts and are passionate about what it stands for," Harry was reported as having told Ms Levin in the discussion, which took place six years ago.
"We feel that the British public and the whole world needs institutions like this, but it can't go on as it has done under the Queen. "There will be changes and pressure to get them right.
"Things are moving so fast, especially because of social media, so we are involved in modernising the monarchy."
Explaining that no one in his family really wants to take on the role of King or Queen, but will do so to fulfil the duty, Harry added: "Is there any one of the Royal Family who wants to be King or Queen? I don't think so, but we will carry out our duties at the right time."
Back in June 2017, the indications were already there that Harry wanted to carve out his own path.
The interview took place a year after he had met Meghan Markle, whom he married in 2018.
Just two years after that, the royal couple turned their backs on the Royal Family and moved across the pond in March 2020.
The pair moved to Montecito in Santa Barbara, a wealthy seaside community in Los Angeles.
