Thousands of black cabs emitting illegal levels of pollution - and hundreds with brake problems - are being allowed on London's streets as a result of Boris Johnson "cosying up" to the taxi trade, it was claimed today.
New figures obtained by the Green Party show 2,898 cabs - one in seven of the capital's black taxis - failed a mid-year inspection prior to the tests being scrapped by the Mayor last year.
A further 1,452 were temporarily taken off the road after problems were found with their brakes, according to the Transport for London statistics.
Darren Johnson said: "These tests are vital in terms of reducing deaths due to air pollution. The black cab trade were very enthusiastic supporters of Boris Johnson during the mayoral election. This looks like pay-back time."
