THE Duke of Cambridge indulged his passion for motorbikes when he visited the Isle of Man TT - but his wife may have not been so impressed.

William, who has a life-long love for the machines, stood feet from the roadside and marvelled at the riders as they screamed past on their bikes.

The duke was making his first official visit to the Isle of Man - a crown dependency - and was joined by the chief minister Howard Quayle and other dignitaries.

William confessed Kate may have been a little sceptical of the intentions of his visit when Laurence Skelly, the Isle of Man government's minister for enterprise, quizzed him about the duchess' views.

The duke replied: "When I said I was going to the Isle of Man for an official visit she said 'really?'."

The Isle of Man TT was first staged in 1907 and is one of the oldest continuous motorsport events in the world.
