Diesels face £10 pollution charge

Plans to charge drivers of diesel cars about £10 to drive into central London to tackle high levels of air pollution, are being considered.

The levy would be on top of the current £11.50 congestion charge for driving into the centre of the capital.

London Mayor Boris Johnson wants the new Ultra Low Emission Zone (ULEZ) to be introduced by 2020.
