Beyond his role as monarch, King Charles is a husband, father and grandfather. He shares a particularly close bond with his five grandchildren: the Prince and Princess of Wales' three children Prince George, Princess Charlotte and Prince Louis, and Prince Harry and Meghan Markle's two children Prince Archie and Princess Lilibet.
His Majesty, known affectionately as "Grandpa Wales" isn't afraid to get stuck in with grandparent duties, and is known for keeping the young royals entertained.

She continued: "He reads Harry Potter, and he can do all the different voices, and I think children really appreciate that."
But did you know that there is a special link between Charles and Prince Louis?

Charles was christened Charles Philip Arthur George, while Prince Louis' full name is Louis Arthur Charles. Aside from the obvious addition of 'Charles' in the young royal's name, the pair also have the shared middle name 'Arthur' which is originally thought to be a nod to the legend of King Arthur and the Knights of the Roundtable.

Louis's milestone moment
Earlier this month, Louis became the first of Kate and William's children to capture the Princess of Wales in a new portrait shared ahead of World Cancer Day.
