Boris Johnson: Airport decision not resigning issue

18 December 2013 Last updated at 14:07 GMT

The Mayor of London, Boris Johnson, says he sees no reason to resign if the Conservatives endorse the expansion of Heathrow airport.

He was asked on BBC Newsnight if he would follow the lead of Tory MP Zac Goldsmith, who said he would trigger a by-election if his party drops its opposition to building a third runway at the west London airport.

Mr Johnson said he didn't know what Jeremy Paxman was talking about.

But Mr Johnson said he continued to support the creation of the Isle of Grain airport in north Kent.

"A new airport in the inner estuary is the only credible hub option left. By keeping it on the table, Davies is saying you have a choice - between a damaging U-turn or a radical new vision for expansion," he said.
