Green party’s Siân Berry says Sadiq Khan can still change his mind and prevent increase in traffic pollution
The mayor of London is being urged to make an 11th hour intervention and halt plans for a new four-lane road tunnel under the River Thames that opponents say would worsen pollution and exacerbate the climate crisis.
Tunnelling equipment is on site on the banks of the Thames, and work on the £2bn Silvertown tunnel is due to start in the coming weeks.
