I am pleased to see that a trial has begun of live CCTV security on the buses. It will mean that as soon as the bus driver knows there is trouble on the bus he can transmit images back to a control centre so that action can be swiftly taken.

This is delivery of another manifesto commitment of Boris Johnson's and one which law abiding bus users will undoubtedly welcome.
