The source told The Times that the transport body is under strict instructions not to disclose anything before polling day, as ordered by the Mayor himself. The same thing happened at the last election when Livingstone failed to reveal before voting that he was increasing the original charge of £5 to the £8 it is today. However, this time his transport manifesto reaffirms his decision to charge the most fuel-inefficient cars £25 a day.
Transport for London is also backing Livingstone against accusations from Porsche that he's exceeding his powers by introducing the £25 charge. Porsche has said it will seek a judicial review of the increase and has argued that it is disproportionate because it would make a “negligible” impact on carbon dioxide emissions.
