Sadiq Khan doubles down on Ulez expansion as Tory MP tries to reverse it

Sadiq Khan has doubled down on his decision to expand the Ulez, after a Tory MP launched a bid to remove the clean air zone from London's suburbs.

Dartford MP Gareth Johnson on Wednesday introduced a private member’s bill to give the Government the power to overturn the London mayor’s expansion of the Ultra low emission zone (Ulez).
