As King Charles is getting cancer treatments every week in London, his son, Prince William, is stepping up to handle the royal duties in his place.

Additionally, William is also looking after his wife, Catherine, who is recovering from planned abdominal surgery, and taking care of their three kids: Prince George, Princess Charlotte, and Prince Louis.

William went to a reccent fundraising event for London’s Air Ambulance. At the event, he talked about his wife and father, thanking everyone for their “kind messages of support for Catherine and for my father, especially in recent days.”

Also at the event was actor Tom Cruise, and Prince William joked with him about not using the helicopters.

“If you wouldn’t mind not borrowing either of the new helicopters for the next Mission Impossible, it would be appreciated,” Prince William said with a smile. He added, “We have all seen on our screens that, how can I put it, you seem to have a different take on normal wear and tear to the rest of us.”

Talking about why the event was important, William joked, “It’s fair to say the past few weeks have been very focused on medical stuff. So I thought I’d come to an air ambulance event to get away from it all!

“But seriously, we’re here tonight to help as many people as possible get top-quality care from the London Air Ambulance’s flying lifelines. As a former pilot for East Anglia Air Ambulance, I know how crucial the work of air ambulance teams is, and how they can save lives by providing urgent medical care wherever it’s needed.

“Here in London, the current helicopters have done a great job. But our city needs new ones. And we’re running out of time. By September, we need two new helicopters, equipped with the latest technology like night vision, to be in the air.”

In addition, the prince was seen talking with Ellen Convery, formerly known as Ellen White, who played over 100 games for the England women’s football team.

King Charles will not be attending public events while he is receiving treatment. When he’s not getting treatment, he is spending time at the Sandringham estate.

The type of canc3r he has hasn’t been shared with the public.
