We know that huge numbers of people in London and across the rest of the country support our case. They agree with us that this proposal would be bad for London - that it is unfair and sends the wrong message about what sort of a city London is whilst having no meaningful benefit on the environment.

We would be very grateful if you could add your name to our online petition which we will present to the Mayor in due course.

Want to do more?

You can also help by writing to the newspaper you normally read or by writing to London Mayor Ken Livingstone, letting him know your opposition to the increased charge. We want to make it clear to the Mayor and other politicians that large numbers of people in London and across the rest of the country are opposed to this unfair charge.
