The nation's favourite grandad is apparently a very gifted mimic who entertains children with spellbinding readings of Harry Potter books.

We are talking about Prince Charles, the future king, who according to his wife, the Duchess of Cornwall, is a brilliant impressionist and actor whose nuanced voices for every character in the books leaves young people in awe.

In a conversation with the Daily Mail, Camilla revealed fascinating details on how the Prince spends quality time with her grandchildren, who are aged between 7 and 9:

"Sometimes, when we are with my husband in Scotland, he reads them Harry Potter."

"And he does all the voices, because he is a brilliant mimic. I'm not very good. I try to do the voices, but acting isn't my forte. But he sits down and they all sit with him."

"I always think they are going to be wriggling around in the bed, but they sit spellbound."

"He's extremely good with children. They love it," she added.
