No such thing as a breath of fresh air

For pupils at more then 800 schools there’s no such thing as a breath of fresh air. That’s because a new study says schools across London are exposed to illegal levels of air pollution which could permanently damage their health. The city’s mayor Sadiq Khan has planned a range of measures including a “toxicity tax” on the most polluting cars. But owners of diesel cars say they are being blamed for a problem created by the government.
