London: Prince Philip, 91, was discharged from Aberdeen Royal Infirmary on Monday after being treated for bladder infection.
Seated in the passenger seat of a Range Rover, the Duke of Edinburg waved to the doctors and nurses while leaving.
The Duke was admitted to the hospital on Wednesday during the royals` annual summer break at Balmoral in Aberdeenshire.
He was admitted after recurrence of the infection, which he earlier suffered before the Diamond Jubilee concert.
The Buckingham Palace had described his admission to hospital as a "precautionary measure."
This is Duke’s third hospital stay in the last nine months.
