Prince Charles celebrated his 70th birthday last week and, in honour of the special occasion, new family portraits of the Royal Family were released. 

The Sunday Times released these exclusive pictures of Prince Charles, or "Grandpa Wales" as his grandchildren call him, and his grandson Prince Louis yesterday. One photo shows Prince Charles holding a laughing Prince Louis, who seems to feel completely at home in his grandfather's arms! Another photo shows Louis staring in fascination at his grandfather's hands, while his mother Duchess Kate holds him in her arms.

The photographs were shot by royal photographer Chris Jackson, who also shot a number of other beautiful shots, including one of Prince Charles sharing a joke with his sons.  

The Prince of Wales often reads "Harry Potter" to his grandchildren

Prince William has described Charles as a "brilliant" grandfather!
