Prince William and Prince Harry undertook as many royal engagements as Queen Elizabeth over the past year.
Although the 90-year-old monarch is cutting back on her duties, she still carried out 80 days of engagements, the same amount as Prince William and just six less than Prince Harry.
William’s wife Catherine was behind all three with just 63 days, according to new information obtained from an analysis of the Daily Court Circular.
Princess Anne had 179 days of public engagements, while her brother Prince Charles had 139 days.
It was recently revealed that Prince Harry wants to step up his royal duties.
The 32-year-old royal proved to himself that he is capable of covering some of his grandmother Queen Elizabeth’s duties during his 15-day tour of the Caribbean on her behalf earlier this year and according to a senior royal aide, Harry wants to do more to help.
Harry’s aide said: "It’s a very different tour for him, doing a lot of things on behalf of the Queen with many more formal bits. But so far it has exceeded his expectations about what he thought was possible.
"He thinks he can do these more formal duties on behalf of the Queen while retaining an authenticity in his work meeting a wide range of people from leaders down to young people."
