Mayor Sadiq Khan is urging leading TV and radio broadcasters to help inform Londoners about poor air quality.

He has written to senior figures at BBC London, ITV London and LBC to ask them to include updates on the quality of the capital’s air during their news and weather bulletins and on their websites and apps.

London breached legal air pollution limits for the whole year just five days into 2017.

Yesterday the mayor announced the first of 50 air quality audits for primary schools in the worst polluted areas in London has been announced.

Mr Khan said: “London’s filthy air poses a significant threat to our health including harming the development of children’s lungs and I’m committee to tackling this issue so Londoners can breathe the clean air they deserve.

“Broadcasters are already doing excellent work covering the threat to public health posed by the capital’s filthy air and I’m asking them to go even further and help empower Londoners to reduce their exposure to harmful pollution. They can do this by providing regular daily air quality information as part of their weather broadcasts.”
