Watch: Charles pulls a pint in Prince of Wales pub
"Nothing is off limits" as the fallout between Prince Harry and the rest of the Royal Family continues according to an expert who has worked with several family members.
Nick Bullen, who is one of the founders of True Royalty TV, said Prince Charles was "hurt" over the ongoing revelations from Harry who most recently said his family neglected him when he was a senior royal.
Ahead of potentially more revelations from the Duke of Sussex, Bullen, who has produced shows like Inside the Royal Wedding and a Diamond Jubilee special on the Queen's horses, told Us Weekly: "It appears nothing is off limits now.
"[It’s sad] that their private family affairs are being aired in public yet again."
The comments came out as Prince Charles and Camilla visited Clapham Old Town in south-west London, with Charles pulling a pint and then taking a sip without removing his mask.
The heir to the throne pulled the bottom of his mask up to take a swig from his freshly poured drink, laughing about the problems with the covering.
Charles and his wife were in the London district to celebrate the reopening of non-essential retail and theatres, popping into the Omnibus Theatre and the Prince of Wales pub, and the Michelin-starred Trinity restaurant.
Pub landlord Dermot Connell said it was exciting to have "the Prince of Wales coming to the Prince of Wales", adding: "It’s good that he’s getting out and about and showing people it’s now safe again to be in the pubs."
Connell has been at the Clapham pub for 30 years, where Charles poured a pint of local brew Sambrook's, before telling Camilla he would not drink it all.
Charles admired the eclectic collections in the pub including Toby jugs, spotting one of the Duke of Edinburgh, which Connell admitted he didn't know he had.
Watch: Prince Charles 'Hurt' Over Harry's Recent Comments About His Upbringing
Charles joked about trying to visit all the Prince of Wales pubs in the country, musing about the "free drink".
Camilla wore a summery multi-snowdrop silk print dress by Fiona Clare and remarked on the lovely weather as spring made an appearance during their trip.
They first popped into Trinity restaurant, which has been in the area for 20 years, and met trainee chefs as well as representatives from the Royal Academy of Culinary Arts.
They chatted to the restaurants suppliers, including M Moen & Sons Butchers and Moxon’s Fishmongers, revealing that Charles prefers mutton to lamb.
Spotting a large mutton on display, Camilla said it was "my husband’s favourite", and Charles could be heard saying that mutton is "so much better than lamb".
They went to Omnibus Theatre and met staff there, before going to the area's fire station and meeting firefighters.
Prince Charles has shrugged off the ongoing claims from his youngest son Harry as he steps up in-person engagements with the restrictions easing around the country.
Harry said he wanted to break a genetic cycle of pain and suffering when he spoke on a podcast with Dax Shepard before his series with Winfrey was released, but Charles did not answer calls for his response when he was next out.
And he has not made any comments related to the five-part series, in which Harry said the Royal Family had neglected him and questioned why his father wanted him to go through the same problems he faced from the media.
Harry is potentially to make new comments on Friday when he joins Winfrey again for a special following up The Me You Can't See series.
The pair will convene a 'town hall' style conversation, and Harry is one of those back to keep talking about his experiences, which is being streamed for free on Apple TV+.
