I would like to request the number of people who have been sectioned under any part of the Mental Health Act 1983, who have a mental health disorder (for example bipolar and schizophrenia.)
We said
Many thanks for your request. I can confirm, following a search of our paper and electronic records, that the Office for National Statistics does not hold the information you have requested. the Ministry of Justice may be able to assist you further. They can be contacted through their website: https://www.gov.uk/government/organisations/ministry-of-justice
