Porsche is to mount a legal challenge to Ken Livingstone's decision to raise the London congestion charge from £8 to £25 for the highest-polluting vehicles. The luxury car company said it believed that the increase was unfair and wouldn't actually help the environment. It plans to write to the Mayor of London this week giving him 14 days to respond before it applies for a judicial review. “A massive congestion charge increase is quite simply unjust," said Andy Goss, managing director of Porsche Cars GB. (source: times online) I do not agree with the increase in the congestion charge but I also do not think its any of Porches's business what the congestion charge rate is.
