Live: Labour leader Ed Miliband speech on social security

Ed Miliband is giving a speech in London in which he will promise to cap spending on social security so that a future Labour government could "turn the economy around".

He is also expected to pledge to allow councils to negotiate lower rents with landlords to cut housing benefit and free up money for housebuilding.
