Powell was ejected through the windscreen and died at the scene. According to the BBC report, at the time of the crash Powell's blood-alcohol reading was over the legal limit, and he was not wearing a seat belt, in addition to talking with his girlfriend on his mobile phone. The official investigation also found evidence of a slow puncture in a rear tyre that, it was suggested, could well have caused a sudden collapse of the tyre with a consequent loss of control of the car.
