Video of Princess Diana's hilarious tactic to reel in a naughty Prince William

Footage of Princess Diana wrangling a young Prince William and Prince Harry has surfaced online, and her technique for taming her eldest son is genius. 

In the newly recovered footage, Prince William and Harry are adorably dressed in army uniforms. Princess Diana holds a quiet Harry in her arms, while William is seen running through bushes.

The princess can be heard asking William to return, but he simply stands his ground. 

In an expertly quipped remark, Diana simply says: 'Alright then, Harry will just have all the fun.' 

William immediately comes running back towards his mother, yelling: 'No, no, no.'

Diana, continuing her act, continues to walk away with Harry still in her arms.

However, Prince William is not far behind.
