Labour leader Ed Miliband has said British politics will be a "poorer place" following his brother David's decision to step down as an MP.
The former foreign secretary, and the elder of the Miliband brothers, announced this morning that he will be moving to New York to become head of a US-based charity.
ITV News political correspondent Alex Forrest reports:
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.
