Britain's Prince Philip has been involved in car crash in which two people were hospitalised.

The 97-year-old was unhurt but was said to be left "very shocked" and shaken following the incident in which his vehicle reportedly overturned.

Queen Elizabeth's husband was driving a Land Rover when the accident involving a Kia happened near the Queen's Sandringham Estate.

According to witnesses, who contacted the BBC, Philip's Land Rover rolled over during the collision.

The witnesses helped the duke from his vehicle.

Norfolk Police said officers were called to the A419 at Sandringham just before 3pm after a Land Rover and a Kia were involved in a collision.

"The male driver of the Land Rover was uninjured. The female driver of the Kia suffered cuts while the female passenger sustained an arm injury, both requiring hospital treatment," the force said.

"We can confirm both casualties from the Kia have been treated at the Queen Elizabeth Hospital in King's Lynn and have since been discharged.

"The road remained open and both vehicles were recovered a short time later.

"It is force policy to breath test drivers involved in collisions. We can confirm both drivers were breath tested and provided negative readings. "

The A149 is a busy road running through the Sandringham Estate.

A Buckingham Palace spokeswoman confirmed the duke was driving when the accident happened.

She added: "He saw a doctor as a precaution and the doctor confirmed he was not injured."

The spokeswoman would not comment on suggestions Philip may have been travelling with a passenger, who is likely to have been his close protection officer.
