Recorded air pollution levels drop at London 'hot spot'
Levels of air pollution on a central London road previously called "a pollution hotspot" appear to have fallen sharply.
The hourly breaches of the European nitrogen dioxide limit at the Marylebone Road dropped from 150 in 2013 to 12 in 2014.
City Hall said the figures show the Mayor of London's policies are working, but air quality campaigners are concerned.
Tom Edwards, BBC London's environment correspondent, spoke to Green MLA Darren Johnson, Simon Birkett of Clean Air for London and Matthew Pencharz the mayor's environmental advisor.
