The reappearance of Harry with his family was discussed on talkRADIO and it is claimed “he was reminded of his old life”.
Charlie Rae, a former royal editor at The Sun, told talkRADIO, said: “Out in the US, Harry looks like a startled rabbit caught in the headlights.”
TalkRADIO host Kevin O’Sullivan added: “We read that Harry was shocked by the frosty reception he got from some members of the Royal Family.
“Some literally turned their back on him. He was stunned by this – I’m not sure why that was a surprise to him.
“It must be occurring to him how frozen out he is, how he has turned his back on his former life.
“There is suggestion that when he came back a few weeks ago, he was reminded of his old life.”
Harry had not formed a “coronavirus bubble” and cut a lonely figure at the funeral service as he sat alone inside St George’s Chapel.
The Duchess of Sussex is expecting their second child and did not make the trip on medical grounds.
Harry was briefly reunited with his brother, Prince William, and they were pictured speaking outside the church behind their face masks.
The Queen’s grandson previously addressed the breakdown of his relationship with William and told Oprah they are on “different paths” and insisted their relationship is “space”.
Royal author Phil Dampier described the conversation between Harry and William as “clearly very strained and only an opening move”.
Harry is scheduled to appear at a statue unveiling in honour of his late mother, Diana, in Kensington Palace on July 1.
The exhibition was planned by Harry and William several years ago to mark what would have been their late mother’s 60th birthday.
But, Mr Dampier added there is “serious doubt” as to whether Harry will fly across the Atlantic for the event.
He said: “I personally don’t think Meghan will return to the UK.
“And there must now be a serious doubt as to whether Harry will come over for the unveiling of a statue for Princess Diana on what would have been her 60th birthday in July.”
