Obama in London

Attention, London: The Obamas have landed. The first couple touched down at Stansted Airport today, ahead of the Group of 20 summit, and were met by Chancellor of the Exchequer Alistair Darling. The Obamas then boarded Marine One for central London, where they’ll stay at the US ambassador’s residence. Before the summit begins Thursday, the president is scheduled to meet with Prime Minister Gordon Brown, Conservative leader David Cameron, and Queen Elizabeth. Brown, the BBC reports, “is keen for world leaders to reach agreement on a new set of rules for regulating global finance as well as measures to boost economic demand and support poorer countries.”
