King Charles was at Windsor Castle when car smashed into royal residence

Three vehicles were involved in the collision, and the police and ambulances subsequently closed the road off at the area near the castle.

A Thames Valley Police spokesperson, said: “Thames Valley Police received a report of a road traffic collision at 7.50am this morning (12/3) on Thames Street, Windsor.

“The road is expected to be closed for some time.

“Anyone with information is asked to contact the force by calling 101 or making a report online quoting reference number 43240115038.”

This crash comes as Princess Kate was pictured leaving Windsor Castle with Prince William on Monday afternoon.

She was attending a "private appointment" while William was going to the Commonwealth Day Service in London.

Windsor Castle was targeted in a protest last month by the anti-monarchy group Republic.

The group posted a photograph on social media of two of their members holding up a banner with the words "End Royal Secrecy" displayed.

The protest took place during the public opening hours and the protesters were paying ticket holders.

Over the weekend, there was an unrelated car crash at the gates of Buckingham Palace.

Armed police arrested the vehicle driver at the scene.

In the early hours of Saturday morning, the police rushed to the palace in London after reports of a "loud bang".

The police surrounded the vehicle and arrested a driver after shouting: "Keep your hands on your head."
