Prince Charles may have to resort to appealing to the public as a family man in order to improve his reputation among citizens.

The Prince of Wales has a hard time winning the approval of the crowd. In fact, based on a poll from YouGov, 56 percent of Brits favor his son, Prince William, to be the next king. Only 13 percent wants Prince Charles to take over the throne after his mother, Queen Elizabeth II, dies or abdicates.

His popularity also took some hits due to several books claiming some negative information about Prince Charles' personal life. Tom Bower's biography, "Prince Charles: The Passion and Paradoxes of an Improbably Life," includes several revelations regarding the second-in-line to the throne that showed him in a bad light.

But according to royal expert Marlene Koenig, Prince Charles can still do something to win the public over and manage his PR crisis. She suggested that the royal prince should show his doting and affectionate side as a grandfather.

"We never see Prince Charles with his grandchildren," the author of "Queen Victoria's Descendants" told News.com. "I think the public would love that, to see grandpa. To see Charles in that way. They obviously take the [official] photos, and I'm sure Prince Louis got one too, but we don't see them."

Rumors have claimed that Prince Charles felt "isolated" from his grandchildren. However, this doesn't seem to be the case as the future king has visited and played with Prince George, Princess Charlotte and Prince Louis.

"We were told Charles does play with his grandchildren in the playhouse and they do come and visit," Koenig continued. "That was kind of comforting, in a way, that he does get to see his grandchildren. We don’t see that — only every once in a while someone will spy pictures. "

"I think he would want to release photos with his grandchildren, but his son William probably doesn't, and at the end of the day they’re his kids," the expert added.

Prince William and Prince Charles reportedly had a rift. The Duke of Cambridge was infuriated when Prince Charles snubbed his mother-in-law, Carole Middleton, over his kids. The royal father and son are also very different. The two don't share the same interests, and Prince William apparently even refused to be part of The Prince's Trust.

Despite winning the crowd's favor, Prince William has no plans of taking over the throne ahead of Prince Charles. "Although like his father, William will be destined to have a far shorter reign than his grandmother, he has said he has no desire to 'climb the ladder of kingship' before his time," Gill Knappett said.
