Nick Clegg is pledging to raise the standard of mental health care as he tries to "bring mental health out of the shadows".
The deputy prime minister dubbed current attitudes towards the insane "outdated" and "stuck in the dark ages".
In a speech launching the Government's new Mental Health Action Plan, which sets out 25 areas where immediate action is called for to improve care, Mr Clegg will say: "All too often, attitudes to mental health are outdated; stuck in the dark ages; full of stigma and stereotypes.
"It's time for us to bring mental health out of the shadows and to give people with mental health conditions the support they need and deserve."
