London mayor Sadiq Khan has announced "dirty" diesel double-decker buses will be phased out from the capital's current bus fleet from 2018.

It comes as the mayor unveiled London's first double-decker hydrogen bus.

Mr Khan also said all new single-decker buses operating in central London would be electric or hydrogen.

City Hall believes "greener" buses will reduce air pollution in the capital, long exposure to which is estimated to cause 9,400 premature deaths a year

The mayor wants all London buses to meet the Ultra-Low Emission Zone standard by the end of 2020.

At least 20 new hydrogen buses will take to London's streets as part of a £10m part-European Union (EU) funded project supporting hydrogen technology.

Transport for London (TfL) will also provide at least £5m in funding.

The new hydrogen double-decker buses will be trialled on London's roads next year while a further 300 "zero emission" buses will be on London's streets by 2020.
