Jul 26 - U.S Presidential candidate Barack Obama continues his European tour and meets British Prime Minister Gordon Brown at his London residence. Following a breakfast meeting with former Prime Minister Tony Blair, Obama met British Prime Minister Gordon Brown at 10 Downing Street. The pair are expected to discuss a range of issues including climate change, Iran and Iraq. Obama's final meeting in the UK will be with opposition Conservative Party leader David Cameron, a possible future prime minister whose party enjoys a strong lead over Brown's Labour Party in opinion polls. There will be no handshake between Brown and Obama at the front door of Downing St. But Obama will have a question-and-answer session with reporters on the street.
