In an interview aired by Good Morning America, the Duke of Sussex said: "Look, I love my family."

The duke flew to London to see his father for just 45 minutes after his illness was made public last week.

In the interview, he was asked if a family illness might have a "reunifying effect", to which he replied: "Yeah I'm sure."

He added: "The fact that I was able to get on a plane and go and see him and spend any time with him, I'm grateful for that."

The duke and his wife Meghan are currently in Canada for events marking one year until the next Invictus Games - the sporting event he founded for wounded servicemen, women and veterans.

Camera crews, led by Will Reeve, the son of the late Superman star Christopher Reeve, are following the couple.

During the interview, Harry said: "Throughout all these families I see it on a day-to-day basis, the strength of the family unit coming together.

"I think any illness, any sickness brings families together."

Harry did not spend any time with his brother Prince William, however, when he flew from his home in California, spending time solely with the King at Clarence House.

The breakdown in the bond between the brothers is often traced back to the early part of Harry and Meghan's relationship, when she and the Princess of Wales are reported to have had a falling out.

Since stepping down from their royal duties in 2020, the couple have expressed significant grievances with the Royal Family through media interviews and Harry's autobiography Spare.

But this week they relaunched their website, replacing their "Archewell" branding with their royal titles the Duke and Duchess of Sussex.

The return to royal branding and use their titles has been met with criticism in light of the decision to quit their roles.

"Their team argue that they are their titles, so why shouldn't they use them? But it is a reminder of the row and debate that blew up when they decided to step away," said Sky News royal correspondent Rhiannon Mills.

Pictures of the Sussexes show Harry going head-first down a skeleton track at 61.5mph, with Meghan cheering him on.

When someone shouted "Meghan, you've got to go", the Duchess replied: "No way."

Harry and Meghan's day at the skeleton track came after they spent Valentine's Day at the Whistler Blackcomb ski resort in British Columbia, where Harry gave sit-skiing a go.
