To CPA: I live in central London (you dont say if you do) and think the congestion charge is the WORST thing that has happened. £1bn of londoners cash has been wasted, I can think of 100 things we need before the CCharge; the second worst thing by the way are all the rock concerts, and parades that Ken organises every other weekend of spring and summer that turn central london into absolute gridlock on. as far as this central londoner is concerned, ken cant disappear quick enough.

Ps. regarding Porsche - they have actually won a lot of respect from drivers from standing upto the bullies at county hall, I wouldnt have considered one before but almost certainly will get one now as a thank you.

If you live in London, particularly central London, and drive a car then you ought to be prepared to pay not just for the petrol you consume but also the 'externalised costs' of your motoring. These include air pollution, CO2 emissions and traffic jams. Why should the rest of us suffer without any compensation?

And CPA, how about voting for Siân Berry, the Green Party candidate for Mayor? You can put Ken down as number 2 and when - as alas will inevitably happen - Siân is eliminated and it comes down to Ken v Boris your vote for Ken will still count.

For many who live in central london, the introduction of the congestion charge has been has been the single greatest contribution to quality of life in recent years. Although I think some
of his political beliefs are ridiculous, Ken Livingstone has done a very good job for London. Because he is the only candidate committed to preserving these advantages, I will be forced to vote for him again.
By bringing this action Porsche seem determined to change the public view of their cars from that of elegant sports cars, to lumbering, polluting, inefficient gas guzzlers. Not a form of rebranding I would have thought to be attractive to them.

How about Ken putting forward a proposal to improve the efficiency of the "average car" - now that would have an impact on the environment.....ah but silly me, there are too many voters with "average cars"

Environmental improvement is about absolute returns not relative. Don't tax the fringes, you have to make a difference to the majority.

At least we can all trust Ken to spend the money wisely.... ha ha!

BJB, London,

It is just another Labour stealth tax on everyone.if they French did it the public would blockade Paris.Why are we letting this happen? Do we the public have no power?Are they untouchable? It just another way taking money from who are forced to live in London or drive a car to work.
Not everyone makes City Money
