High court rules Ulez expansion legal

London's Mayor Sadiq Khan has got the green light to extend his controversial ultra low emission zone, Ulez. The High Court has thrown out a challenge by five Conservative-led outer London councils to stop it expanding to cover the whole of the city.

The scheme hits drivers of the most polluting cars with a £12.50 daily charge. Its expansion was blamed for Labour's failure to win Boris Johnson's Uxbridge and South Ruislip seat in last week's by-election.
