The Mayor of London has said he will join a legal challenge to the Government's plans if MPs "vote Heathrow" in the House of Commons on Monday, 25 June.

The leaders of Hillingdon, Wandsworth, Richmond, and Windsor & Maidenhead councils have already signalled they will be exploring the possibilities of a judicial review of the Government's intention to build a third runway at Heathrow if the plans are approved.

Other councils in London and the south east are also expected to join that legal battle - which will centre on both the environmental damage and harm to public health if the new runway is approved.


The four councils have argued that Heathrow is the wrong place for airport expansion in the south east. The boroughs argue that existing noise levels and already poor air quality standards render a third runway "undeliverable and inconceivable".

Cllr Ray Puddifoot, Leader of Hillingdon Council, said: "Throughout the whole consultation process, the Government has failed to address the concerns not only of the impacted communities but also the advice from the Transport Select Committee. Now is the time for councils and groups to come together to stop this in the only way left to us - the courts. We are delighted the Mayor is joining and urge other boroughs to do the same."
