Boris Johnson 'held back' negative findings of air pollution report

Report's author says City Hall publicised positive conclusions but held back the finding that deprived schools were disproportionately affected by toxic air

The author of a report on how London's illegal air pollution disproportionately affects deprived schools has said City Hall under Boris Johnson held back the study's negative findings, while publicising the positive ones.

The Guardian revealed an unpublished Greater London authority (GLA) report on Monday that showed how deprived schools in the capital were disproportionately affected by toxic air, leading the new mayor, Sadiq Khan, to accuse Johnson of burying the report.
