A soldier from the Queen's Guard turned his rifle on a tourist who pestered him outside Windsor Castle.

A video shows the moment he suddenly snapped when a man who had been mimicking the soldier's walk placed a hand on his shoulder.

"Step back from the Queen's Guard", the soldier shouted as he pointed his bayonet at the man, who quickly jumped out of the way.

The Ministry of Defence described the soldier's actions as an "appropriate reaction" and said he would not be disciplined.
