The chief executive of the company that installs the majority of speed cameras on Britain’s roads was banned from driving for six months today after admitting driving at more than 100mph.

Tom Riall, the boss of Serco’s civil government division, which supplies and installs the Gatso fixed radar cameras to police forces, was traveling at 102.9mph on the A14 in Newmarket, Suffolk, just before 1pm on 4 January, magistrates in Sudbury heard. The speed limit on the dual carriageway is 70mph.

Riall, 49, had two other driving convictions from the last three years, including another speeding offence, the court heard, meaning the six-point penalty imposed by magistrates took him past the 12-point mark, incurring the ban. He was also fined £300…

Serco, which has installed about 4,500 speed and traffic light cameras since 1992, began as a defense firm and over the years has won a series of lucrative government contracts in areas which also include prisons, leisure centers and NHS facilities.
