Prince William has come under renewed pressure since the start of the year after the Royal Family was struck by a series of health crises.

Prince Willam has been showing off a pivotal trait he shares with his late grandmother, Queen Elizabeth II, in recent months, according to a royal expert.

The Prince of Wales has been forced to come to grapple with the King and his wife Kate, the Princess of Wales being diagnosed with cancer within weeks of each other.

After taking a temporary leave of absence from his duties to be by Kate’s side, he returned to his public engagements last month.

Royal commentator Emily Nash noted William appeared to show the same ability the late Queen had to “compartmentalise” his feelings to be able to resume his duties despite the difficult period.

Nash said: “What I found really interesting watching William recently is how much he shares his late grandmother’s ability to compartmentalise.

“If you remember back to those early engagements in the early spring, I’m thinking in particular to him turning up to that event with Tom Cruise – behind the scenes, all manner of stuff was going on.

“And yet he turns up, smile on his face, he’s able to get on with things.”

Speaking to Times Radio, the Hello! Magazine royal editor said the Prince of Wales is notably “private” about his family – but he has likely appreciated the public support shown to him and Kate since her diagnosis.

She continued: “Obviously, everywhere he goes now people are offering him good wishes for the Princess, asking after her.

“And we know he’s a very private man, he’s not about to give chapter and verse on things, but they’ve also shared messages about how much the outpouring of support means to them.

“So I think they’re drawing strength from each other but also from the wider public and the response to her illness.”

During a visit to the Isles of Scilly, where he’s known as the Duke of Cornwall, William provided a rare update on Kate’s condition.

Asked about how the Princess of Wales is, the Prince said she is “doing well” since her cancer diagnosis.

The Princess underwent abdominal surgery in January, with the Palace confirming she was not expected to resume her duties until Easter at the earliest.

But in March, Kate released a video in which she confirmed she was receiving treatment after tests found that “cancer had been present” after her surgery.
