I learn from your Diary (NCE 8 January) that Ken Livingstone has recounted how he had been surprised at the absence of gridlock on Tower Bridge on the first day of congestion charging.
However, the reason for there not having been a vehicle in sight is simple - all the traffic was stuck in Kennington Lane.
And still is!
I would urge any other urban authority contemplating a congestion charging zone to make sure that there is a fully competent circumferential route in place before they switch on TV cameras in the centre.
