Mayor of London Sadiq Khan has launched a trial of the world's largest air pollution monitoring network

It will include 100 monitors in schools, on streets lamp posts and at known hot spots.

Mr Khan is following through on promises he made during his Mayoral campaign in 2016.

Speaking to us at the time from his former constituency of Tooting, he explained why air quality is at the top of his agenda.
