Prince Charles has been a rock for Prince Harry and Meghan during 1st year of marriage, director says

Charles has helped Meghan and Harry “soldier on," a documentary director said.

In the face of all of that Charles, 70, has told Harry and Meghan to ignore the controversies and "soldier on," John Bridcut, the director “Prince Charles at 70” on PBS, told DailyMailTV.

Bridcut said he believes Charles would advise Harry and Meghan to "just carry on doing the job," as the Prince of Wales has done in his own life.

“He would apply himself and just carry on doing the job and soldier on and that's what he's done and it's borne fruit,” said Bridcut,

Bridcut noted that Charles has been able to use his experience of public scrutiny around his relationship with Harry’s mother, the late Princess Diana, to help guide the couple.

“There is a close relationship between father and son and I'm aware that he gets along very well with both the daughters-in-law,” Bridcut said, adding that he has seen Harry in particular "become a real champion of his father ."

"Charles is being completely supportive -- and could be seen in the very touching way in which he was involved in the wedding ceremony itself, which was sort of all quite understated," Bridcut said. "It was all very last minute of course the way things turned out."

"But what Camilla [the Duchess of Cornwall] says in the film, that I felt very strongly when I watched it myself, with the way he held out his hand for Meghan's mother and that moment was completely unscripted and spontaneous, but totally typical of the man actually," he added. "He doesn't advertise this but he is a very sensitive man and I've seen that myself a lot."

Meghan and her father-in-law shared a sweet moment this month when the royal family gathered for the Commonwealth Day service at Westminster Abbey. She and Charles were photographed sharing a laugh at the service.
