Outer London boroughs could be offered a referendum on Sadiq Khan’s expanded Ultra Low Emission Zone (Ulez) scheme under Tory a mayoral hopeful.
If selected as a candidate and succesful elected in next year’s elections, Samuel Kasumu, a former adviser to Boris Johnson, would grant boroughs affected by the expansion - including Bromley, Bexley, Harrow and Hillingdon - a vote on whether to remain in the zone or leave it.
