- The Queen's biographer Andrew Morton said she wouldn't have allowed people to kiss her.
- King Charles has allowed well-wishers to kiss him on the cheek and the hand through the years.
Royal biographer Andrew Morton says one key difference between Queen Elizabeth II and King Charles III was their interactions with the public.
Morton's latest book, "The Queen: Her Life," was published by Grand Central Press on Tuesday. Morton is a well-known royal expert, having previously worked with Princess Diana on her biography, "Diana: Her True Story," which was published in 1992 and revised in 1997 after her death.
Speaking to Insider, Morton shared his thoughts about the newly-appointed king, who took the throne after Queen Elizabeth died on September 8 at the age of 96.
"He lets people kiss him, which the Queen would never do. So there's a different kind of style there," Morton said of Charles.
A woman was photographed kissing the king's hand outside Buckingham Palace on September 9 as he greeted members of the public mourning the Queen's death.
The moment was also captured in a video clip shared on Twitter by the "Today" show.

It wasn't the first time the king allowed a well-wisher to get close to him. Before he was king, Charles was often seen accepting a kiss on the cheek or the hand by members of the public during royal walkabouts. For example, in 1977, a 16-year-old girl was photographed kissing the then-titled Prince Charles' cheek in Perth, Australia, and he appeared to smile during the encounter.
Morton went on to say that Charles will likely have a "more dynamic" style when it comes to his role as monarch.
"The Queen was in her nineties and had a very much reduced agenda. The king, I think is going have to go at pace, even though he's 74 himself," Morton said.
Morton said he predicts that Charles will visit the Commonwealth countries "as quickly as possible" to demonstrate his role as Head of State. He added that the next key item on the king's agenda will be ensuring that his coronation represents "the whole of multicultural, multi-faith Britain."
"I mean, when the Queen was crowned, it was basically a white Protestant country. Now it's made up of many faiths, many races. And how does King Charles represent that?" Morton said.
In his first speech as monarch on September 9, the king acknowledged that the UK has "become one of many cultures and many faiths" over the past 70 years.
"Whatever may be your background or beliefs, I shall endeavor to serve you with loyalty, respect, and love," he said.
The king will be coronated at London's Westminster Abbey on May 6, 2023, Buckingham Palace announced in October.
"The Coronation will reflect the monarch's role today and look towards the future, while being rooted in longstanding traditions and pageantry," a palace spokesperson said in a statement at the time.
Buckingham Palace did not immediately respond to Insider's request for comment.
