Green party candidate for Mayor Jenny Jones and party leader Caroline Lucas have accused Boris Johnson of “deceptive efforts” to cover up London’s air pollution.
Official figures suggest around 4,000 people a year die prematurely in London because of poor air quality.
The pair visited Lewisham on Tuesday accompanied by Lollipop men and women who warned passersby about the capital’s polluted air.
Jones said: “Air pollution is now the second biggest killer in the Capital and is rapidly emerging as the number one public health issue for Londoners.
“We simply cannot go on as we are. It is a scandal that the response of our current Conservative mayor has been to try and hide the problem rather than take steps to deal with its causes.
“By electing more Green Assembly Members, London can help ensure that this crucial issue is given the attention it needs by City Hall.”
Lucas added: “During the campaign, Jenny has already changed politics for good.
“Her calls for greater transparency of politicians’ pay and tax have rocked Westminster as well as City Hall, and London’s political map has been redrawn by the prominent, consistent involvement of a strong Green voice.
“By voting for Jenny and more Green Assembly members, London can becoming a model for the world in addressing climate change and fighting inequality.”
Candidates for Mayor include Jenny Jones (Green party), Ken Livingstone (Labour), Lawrence Webb (UKIP) Boris Johnson (Conservative) and Brian Paddick (Liberal Democrat). A full list of candidates can be found here.
