Shadow chancellor wants 4G to fund 100,000 new homes
Shadow chancellor Ed Balls has called for 100,000 new affordable homes and a two-year stamp duty holiday for first-time buyers to kick-start the economy.
He said the £3bn to £4bn funding should come from the 4G mobile spectrum sale.
Mr Balls used his speech to Labour's conference in Manchester to stress the need for "urgent" action on growth.
