This is the moment a shocked tourist was pushed out of the way by a member of the Queen's Guard at Windsor Castle.

The women screamed in shock as she was shoved from behind by the soldier, who was wearing his ceremonial bearskin hat.

The tourist didn't appear to be injured and managed to remain on her feet despite the mighty shove.

Tourists like to have their photographs taken with the soldiers who are wearing their ceremonial uniforms.

However, if someone impedes their progress, the soldier would normally shout "Make way for the Queen's Guard."

In a statement the Ministry of Defence said: "The Household Division is proud to guard Her Majesty and honoured that people come from around the world to watch our ceremonial spectacle.

"The ropes are there to protect both the public and our soldiers; please stay behind them."

The Queen's Guard, manned by fully-trained, serving soldiers, have more than 350 years of history and have defended monarchs since Charles II took the throne after the English Restoration in 1660.

The Guards consist of five infantry regiments — the Grenadier, Coldstream, Scots, Irish and Welsh Guards — and two regiments of the Household Cavalry — the Life Guards and Blues and Royals.

In 2015, a soldier turned his rifle on a tourist who grabbed him outside Windsor Castle.

To giggles from his friends, the Asian man marched alongside the serviceman and placed his hand on the soldier's shoulder.

But the soldier suddenly spun round and pointed his weapon at the tourist, shouting: "Get back from the Queen's Guard!"

Last year a Queen's Guard yelled at a sightseer who got too close to him while posing for a picture at Windsor Castle.

The soldier was closing one of the castle gates before yelling at the tourist to "stay away".
