Boris Johnson slams expansion of Ulez that he created while mayor

Boris Johnson has attacked Sadiq Khan and his “bone-headed” plans to expand London’s ultra-low emissions zone (Ulez) in his latest Daily Mail column.

The former prime minister, who came up with the initial Ulez scheme when he was mayor of London, has labeled Mr Khan’s plans to expand it to cover most of Greater London on August 29 as “insane” and “so transparently wrong and unnecessary”.
