Ken Livingstone has now announced that from 27 October cars with the highest greenhouse gas emissions, such as some so-called ‘Chelsea tractors’, will pay a daily charge of £25 to drive in the central London Congestion Charge Zone. Ken’s announcement, was made at his weekly City Hall press conference, where he was joined by Tony Juniper from Friends of the Earth, who said that ‘Charging gas-guzzling vehicles more to drive in central London is extremely welcome and supported by most Londoners.’ Read more at Gas guzzlers - Ken gives the go-ahead for world leading scheme

It has been a feature of the build-up to the election that any organisation or individual who backs Ken, or gives him credit for what he has done for London, or criticises Boris Johnson, can find themselves aggressively targeted by Johnson’s allies.

Johnson’s supporters now operate the policy of trying to silence anyone they don’t agree with by claiming that their views are illegitimate or bought.

We’ve seen repeated examples of this in the past. Boris Johnson earlier launched a general attack on community leaders declaring “When anything is signed by so-called community leaders I take it with a big pinch of salt.”

Today, Andrew Gilligan has launched a renewed attack on a variety of individuals, leading figures from the black communities, and environmentalists from Greenpeace and Forum for the Future, on exactly this basis.
