UK government sued for third time over deadly air pollution

Ministers accused of 'stubborn failure' to tackle widespread and illegal levels of air pollution, which cause 40,000 early deaths every year

The UK government is being sued for a third time over the widespread illegal levels of air pollution, which cause 40,000 early deaths every year.

Environmental lawyers ClientEarth have already defeated ministers twice in court, forcing a new pollution plan to be drawn up in July. But ClientEarth believes even the latest strategy does not meet the legal requirement of banishing toxic air in the "shortest possible time", as EU law requires.
