Car maker Porsche is to seek a judicial review of the decision to charge drivers of Band G cars to £25-a-day to drive into London, according to reports.
Andy Goss, managing director of Porsche GB, has described the charge as "quite simply unjust" warning that "thousands of car owners will be hit by a disproportionate tax which clearly will have a very limited effect on CO2 emissions."
Liberal Democrat Mayoral candidate Brian Paddick said the company "have a point: this has become an emissions charge, not a congestion charge and an ineffective one at that. If it ends up in court, it will be Londoners who pick up the tab."
A spokesman for Ken Livingstone’s campaign team said the charge was "matter of democratic choice" adding "Londoners will have a clear choice on this on May 1st, with Boris Johnson and Brian Paddick opposing a £25 charge on gas guzzlers for driving into central London and Ken Livingstone committed to introducing it, and Londoners who want to see this policy implemented should vote for Ken on May 1st so that this scheme can go ahead."
Critics of the scheme have claimed it will not reduce carbon emissions and is unfair to those who are unable to afford a new, low emission vehicle.
