The Prince of Wales staged a dress rehearsal to teach the Duke of Cambridge the intricacies of hosting an investiture, complete with a sword sent up to Scotland from London.

Charles held the trial run for William during a family holiday at Birkhall in Scotland on September 26.

The heir taught his son how to dub a new knight with a blade brought from the capital along with Prince George's pram.

William carried out his first investiture ceremony last week at Buckingham Palace and the training from his father was a success as the ceremony passed off apparently without any problems.

This latest issue of Time magazine describes how Prince Charles staged a "dress rehearsal, using a sword that has been dispatched to Scotland from London along with George's Silver Cross pram."
