Cameron Reassures Navy Over Defence Review

Prime Minister David Cameron has arrived in Canada ahead of a summit of the G8 group of leading world economies at which he will urge fellow leaders to press ahead with reforms to global trade and financial governance and to live up to promises on aid. Mr Cameron's first international summit since his election last month will also give him an opportunity for his first face-to-face talks with US President Barack Obama, in which Afghanistan and the BP oil spill will be high on the agenda.
