Boris Johnson personally raised the prospect of taking legal action against the Government of David Cameron to speed up a review of London airport expansion.

The Evening Standard reported that the Mayor of London told the Prime Minister that he could go to the High Court to bring forward a government-commissioned study into Britain’s airports which is only due to report fully after the 2015 election. Meanwhile, Gatwick bosses today unveiled plans for a second runway which is sure to create a full-blown clash with Heathrow over which airport should expand to meet the South-East’s aviation needs.
