Bill Clinton has congratulated David Miliband on his appointment with the International Rescue Committee.
He said: "I congratulate the IRC on the appointment of David Miliband as its president. I have known David almost twenty years. He is one of the ablest, most creative public servants of our time."
David Miliband was nearly Prime Minister, and nearly Labour party leader, but his brother's rise has led him to take a back seat.
David Miliband will resign as an MP to take up a job in America, a move which is set to be announced today.
