The Labour leader knows that going all out to stop Ulez would damage the fragile Labour coalition on climate matters
Does Sir Keir Starmer really want to stop the expansion of London’s Ultra Low Emission Zone (Ulez)? That is the question hanging over the Labour Party’s divisions on the issue.
Certainly until the last few weeks there was almost no public indication that the Labour leader was a critic of the policy pursued by one of his most prominent regional mayors.
But then came the surprise failure to take Boris Johnson’s old seat of Uxbridge and South Ruislip 10 days ago with voters appearing to raise two fingers at Ulez.
And so followed a period of public distancing by Labour’s most senior MPs from London mayor Sadiq Khan’s proposal to expand the area to cover all of the capital’s boroughs.
