London drivers ditching diesel cars six times faster than rest of UK

Abandoning of polluting vehicles has accelerated since expansion of ultra-low emission zone announced

Drivers in London have abandoned diesel cars six times faster than those in the rest of the UK since Sadiq Khan announced plans for a massive expansion of the London's clean air zone.

Research released days before London's ultra-low emission zone (Ulez) is rolled out across the capital shows there are about 128,000 fewer diesel cars on the city's roads than in 2017, when the mayor announced plans to create one of the biggest clean air zones in Europe.
