"Ministers would like us to believe that community treatment orders mean people with mental health problems will be getting extra attention and support. But they won't," said Mind's policy director Sophie Corlett.
"This legislation is dangerous," she continued, "the result of it will be that people with mental health problems won't get the help they need.
"The government are ploughing ahead in spite of all the evidence. Psychiatrists oppose the government proposals, nurses oppose them, mental health organisations oppose them, and, crucially, patients oppose them.
