Thomas Markle is likely "very sad" to be missing out on yet another special family occasion because of his strained relationship with Meghan Markle and Prince Harry, a royal expert claimed.

The former television lighting director has been effectively estranged from his youngest daughter since after her wedding to Harry in 2018.

He was due to fly to the UK to walk her down the aisle, but news of an agreement with the paparazzi paired with a heart attack days before the ceremony prevented him from attending.

Markle is not believed to have seen the Duchess of Sussex since – and he has repeatedly complained about never meeting his grandchildren, Prince Archie and Princess Lilibet.

With Lilibet's birthday looming, royal expert Phil Dampier spoke of the distress Mr Markle shares with King Charles as he misses out on yet another special occasion.

Speaking to The Sun's Royal Exclusive show, Mr Dampier said: "It is amazing that she's already three but there is this underlying sadness of course because of the rift that the King is not seeing his grandchildren.

“I think he's only met Lilibet possibly once and Archie only a couple of times and they are seventh and eighth in line to the throne, growing up in California on the West Coast of America with American accents and they just don't see them.”

During her bombshell interview with Oprah Winfrey in 2021, the Duchess claimed her father had lied to her about speaking to the British press in what she dubbed a "betrayal" she couldn't "reconcile."

Mr Dampier added: "So that is the underlying sadness and whether they're going to one day heal this rift, we don't know, but at the moment I don't think there's much prospect.”

The royal expert also argued Harry and Meghan face the prospect of intense questioning from Lilibet and Archie when they are older on the lack of contact with both families.

He said: "When they get a bit older, are they going to start asking questions ‘How have we got to this situation’, ‘How is it I don't see my grandparents’, ‘How is it I don't have anything to do with the Royal Family?’

“When they get old, that's probably when the problem is going to start and it's going to be difficult for them.”

Lilibet, who will be turning three on June 4, is believed to have met the King in person only once when her parents brought her and Archie to the UK to celebrate the late Queen's Platinum Jubilee in 2022.

While Archie was born in the UK and met his grandfather on multiple occasions, he was barely six months old when he moved to North America with his parents.

There have been an untold number of well-publicized royal scandals over the years, many points in history where the ongoings of the British monarchy have dominated newspaper headlines and whipped the general public into a frenzy.

The current state of affairs must surely rank among the most tantalizing.

Not only has the whole saga regarding Kate Middleton’s recovery from a mysterious abdominal procedure captivated all and sundry since January, but King Charles also received a shock cancer diagnosis. That’s not to mention the ever-present controversy where Prince Harry and Meghan Markle are concerned.

In most other decades the reigning monarch’s fight against cancer would be the focal point of the media attention. It speaks volumes, then, that the maelstrom of speculation surrounding Kate has virtually pushed all other topics into the shadows.

It could be argued that the royals only have themselves to blame for the intense scrutiny placed upon Kate’s recovery. Aside from confirming that the Princess of Wales was undergoing a “planned abdominal procedure” in January, adding that she would be out of action until around Easter time, the Palace has been thrifty to the point of arousing suspicion with its updates.

Just what Kate was suffering from that required surgery remains unknown to the public. Compounding the sense of confusion was the fact that Kate – until last week – hadn’t been seen since Christmas.

And if the vacuum of concrete information brought the pot of speculation to boiling point, the debacle surrounding the image of Kate and her children released to mark Mother’s Day in the UK blew the lid off with such force that the various conspiracy theories suddenly became of interest worldwide.

Among the mostly hotly debated possibilities was that Kate and Prince William were experiencing marital troubles, the likes of which had left Kate with no option but to withdraw from the spotlight until a solution could be found.

At this stage we’d be remiss in our duties if we didn’t point out that any and all reports of William and Kate’s romance being in crisis remain unconfirmed. That said, the topic has generated enough attention to make it an undeniable fact that the public are at the very least extremely intrigued.

The crux of the aforementioned marital bother William and Kate are purported to have found themselves in centers around the rumor that William had engaged in an affair with Rose Hanbury, the Marchioness of Cholmondeley.

According to reports, Rose and her husband David Rocksavage, the 7th Marquess of Cholmondeley, have been in William and Kate’s social circle for some time. Once upon a time, the ever-reliable Sun newspaper tried to flog speculation that Kate and Rose had a falling out (leading to a not-insignificant amount of people claiming the cause was an affair between Rose and William).

And it seems as though that candle of scandal continues to burn even today, some five years since The Sun published the aforesaid information.

Last week there were multiple articles written about Rose – in the midst of the media throng to find out where Kate Middleton was – with some news outlets even being accused of ‘soft-launching’ the Marchioness in preparation for a time wherein her alleged affair with William became official news.

Of course, the outlandish rumors appear to be just that… outlandish. Even so, Rose Hanbury herself was bothered enough to break her silence and firmly deny that any affair had ever taken place.

As per reports, Business Insider reached out to Rose’s lawyers this weekend for comment. The reply they got read: “The rumors are completely false.”

So there you have it… case closed, perhaps, maybe, for now.
