Tory candidate for London mayor has Trumpian attitude to climate, says Khan

London mayor expected to criticise Susan Hall in speech launching panels on school roofs

Sadiq Khan will accuse his Conservative rival in the race to be London’s next mayor of being “Trumpian” over the climate crisis, as he announces plans for solar panels on schools.

Khan is expected to acknowledge resistance to his expansion of the ultra-low emission zone (Ulez) in a speech on Friday but insist that he still intends to “go further”.
