Boris Johnson expects an extra 30,000 vehicles to enter the Western Extension Zone once he scraps the charge there next year.
The figures released in response to a question from Murad Qureshi anticipate as many as 33,150 extra vehicles entering the zone each day.
To put that into context, there are just 21,000 licensed buses and coaches in the whole of London.
According to the Mayor:
"TfL estimates that removing the western extension to the Central London congestion charging scheme would increase traffic entering the extension area during charging hours by 10-15% over current levels. Traffic circulating within the area would rise by some 7-12%."
When the Western Extension was brought in around 30,000 fewer vehicles entered the zone.
This initially led to a 17-24 per cent reduction in congestion. However, that has since been reversed after a series of street and property works began in the area.
As a result of this, Kensington and Chelsea remains one of the most congested boroughs in London.
And no matter what kind of spin Boris Johnson puts on that, this will only now get worse.
