The problem of mental illness in the UK is the "biggest unaddressed health challenge of our age", Labour leader Ed Miliband has said.

It "blights the lives of millions", costing UK business £26bn and the NHS an extra £10bn a year, he said.

He criticised some celebrities for reinforcing the taboo around mental health and called for a culture change.
