David Cameron Defends Foreign Aid Amid "Austerity"

The British Prime Minister made the defense ahead of a "Hunger Summit" at Downing Street.

On Sunday, the Prime Minister will host a "hunger summit" at 10 Downing Street, with African leaders, other heads of state, charities and athletes including Somali-born British gold medal-winner Mo Farah to discuss ways to combat malnutrition in the developing world.

Ministers want progress on tackling hunger among children around the world to be as much of a legacy of London 2012 as the sporting inspiration the Games have provided.
