London: The Duke of Edinburgh has been taken to hospital as a "precautionary measure", media reports said on Wednesday.
The 91-year-old Prince Philip was driven by ambulance to Aberdeen Royal Infirmary while staying at Balmoral with the Queen, BBC quoted a Buckingham Palace spokesperson as saying.
He is not thought to be in a critical condition, the report added.
Barely two months ago, Prince Philip was taken to hospital with a bladder infection shortly before the Diamond Jubilee concert (June 4). He is now being cared for in an National Health Service (NHS) hospital. But he will also be seen by his own private doctor.
This is for the third time in last nine months that Prince Philip has to visit hospital. On Christmas, he had to spend four days in hospital, following an operation to clear a blocked heart artery.
He was last seen at public engagements in the seaport town of Cowes earlier this week.
