Police have confirmed a nine-month-old baby boy was inside a car which collided with the Duke of Edinburgh's land rover.

As investigations continue into the crash involving a Kia and a Land Rover driven by the Duke, police confirmed the Kia was carrying a baby boy but that he was not injured in the collision.

The driver of the Kia, a 28-year-old woman, received cuts to her knee and the second passenger, a 45-year-old woman, suffered a broken wrist.

Both women were treated at the Queen Elizabeth Hospital in King's Lynn and were discharged last night.

The Duke was uninjured in the crash but is said to be shaken up by the incident.
