A Grenadier Guard has been caught on camera busting some moves outside Buckingham Palace, but the soldier is expected to receive disciplinary action for his dancing.
The three-minute video clip shows the soldier, wearing his his red tunic and bearskin, perform a series of stunts for onlooking tourists.
The guard is first seen marching up and down the gravel forecourt, before breaking into elegant pirouettes.
He can then seen picking up something from the floor and putting it in his pocket.
The soldier launches into a comical strut and pretends to polish his guard box with his knuckles.
Tourists can be heard laughing in the background, with one child saying: "Look at him spinning. That’s really silly. Do you think he will get told off for it by the policeman?"
His comical antics come to an end once the guard retreats to his box after giving his fellow guardsman a thumbs-up.
Although the guard's antics were hilarious for the tourists, a military source has warned that senior officers will not be amused.
A spokesman for the Army and Ministry of Defence told the Daily Mail an internal investigation has been launched and said: "Anyone who is found to fall short of the Army’s high standards can expect to face appropriate action."
Orders for the duty are read out before each two-hour ‘shift and state that: "You may not eat, sleep, smoke, stand easy, sit or lie down during your tour of duty."
The Queen was not in residence at the time as she is currently staying in Scotland.
