In this week's show, we look at Heathrow as the government announces it will be expanded with a third runway. We ask — how was it that green politics failed to stop the green light?
We discuss how Britain has responded to Gaza. As the Guardian calls for David Miliband to drag the Israeli ambassador in for a stern "conversation without coffee", what exactly should the country be doing and how much difference can it make?
And finally, as Barack Obama gets ready to take up that new job — as leader of the free world — we ask which of the British parties is best-placed to exploit his promise of change. Is Gordon Brown or David Cameron more like Barack Obama?
Joining leader writer Tom Clark in the Guardian's new King's Cross studios is our columnist Jonathan Freedland . He thinks Britain needs to help to get rid of Gaza's blockade.
The Guardian's executive comment editor, Georgina Henry, meanwhile, says Heathrow expansion is entirely incompatible with the government's supposed green aims.
And political correspondent Allegra Stratton thinks that it is Gordon Brown — with his street campaigning in Kirkcaldy — and not the public schoolboy David Cameron, who closely resembles Barack Obama.
Plus we hear from Washington from Guardian America's editor, Michael Tomasky, who thinks that Obama wants to reintroduce America to the liberal idea of the common good.
