A few years ago in my constituency, a taxi driver died as a result of a fracas in a private-hire taxi. Bolton is the first local authority to install miniature CCTV cameras on the windscreens of black cabs and private-hire vehicles. That successful experiment has been made permanent. The scheme is self-financing in that taxi drivers have to lease the cameras, but the cost is offset by their reduced insurance premiums. Does my right hon. Friend agree that that brave experiment should be spread throughout the country?
