Prince Harry has said “incessant” intrusions into his private life have made the line between his personal and public affairs “almost non-existent”.
The young royal, who is in Florida for the Invictus Games, said that “everyone has a right to privacy” and interest in him verged on “unnecessary”.
He told the BBC’s Andrew Marr programme that he intended to use his family’s “very privileged” public position to promote good causes.
The Prince said: “Sadly, that line between public and private life is almost non- existent any more and we will do our best to ensure that there is a line.”
“We are completely aware that we are in a very privileged position and I will spend the rest of my life earning that privilege and trying to bring a spotlight on to things and causes that really matter to me and hopefully matter to a lot of other people as well.
“Everyone has a right to their privacy and a lot of members of the public get it, but sadly in some areas there is this incessant need to find every bit of detail about what goes on behind the scenes.”
The former Army officer’s championing of injured veteran’s causes echoes the commitment to charity work of his late mother, Diana, Princess of Wales.
Harry told the programme the Invictus Games – of which he is a patron – was not an “unpopular” cause of the sort his mother is said to have committed herself to, but one he felt needed more of a spotlight.
In a newspaper interview, he also said he was subconsciously trying to fill the “void” left by her when she died in 1997.
He said he thought she would be proud of him, adding: “That probably is subconsciously very much part of my mother – trying to fill that void.”
Addressing accusations of being workshy that have dogged him and his brother, the Duke of Cambridge, this year, Harry said: “I don’t get any satisfaction from sitting at home on my arse.”
The royal said he wanted a job after leaving the Army but could not find one with which he could combine his royal duties.
