Iain Duncan Smith defends disability welfare reforms

Iain Duncan Smith has defended changes to the welfare system, including disability benefit reforms.

The work and pensions secretary has said the raft of changes should save the taxpayer £50bn by the end of this Parliament.

He told the Andrew Marr Show: "I think most taxpayers... will want to know the money they pay goes definitely to those who need that support."
