Doctors urge politicians to stand firm on schemes to tackle air pollution

Exclusive: hundreds of consultants, GPs and others write to Keir Starmer and Sadiq Khan over Labour's position on Ulez

Hundreds of doctors have urged politicians to stand firm on initiatives to tackle air pollution, warning that they see its devastating health consequences" in patients on a daily basis.

Air pollution is the single largest environmental risk to public health, linked to between 28,000 and 36,000 UK deaths a year. The estimated cost to the NHS and social care of air pollutants is estimated to be 1.6bn between 2017 and 2025.

Keir Starmer and other senior Labour figures have prompted alarm among health professionals after they called on the London mayor, Sadiq Khan, to reflect on the expansion of the capital's ultra-low emission zone (Ulez) after the Uxbridge byelection defeat.
