A couple claim to have photographed Top Gear presenter Jeremy Clarkson talking on his mobile phone while driving at 70mph.

Adam Blake, 22, and Hayley Byford, 21, say they saw Clarkson on the phone as he whizzed along in a rare 1970s 6.3-litre green, left-hand drive V8 600 Grosser Mercedes on the M40 in Oxfordshire.

Mr Blake told the Mirror newspaper: “We could not believe that we’d caught him out. I used to watch him every week on Top Gear and he was always banging on about the new driving laws.

“Everyone knows you can’t use your phone at the wheel. Perhaps he thinks he’s above the law.”

Drivers caught using mobiles at the wheel face three points on their licence and a £60 fine.

Mr Blake added: “My girlfriend saw he was on his mobile. She grabbed hers and took a picture of him.”

The newspaper claimed it later confronted Jeremy at his Chipping Norton home where he first denied being in the car and, on seeing the picture, said: “Er, that isn’t a phone.”

Jeremy then reportedly said: “Look, I write a column for another newspaper. I’m not allowed to talk you.”
