Question to the Ministry of Justice:

To ask His Majesty's Government for how long is it lawful for a prisoner to be kept in solitary confinement.

Prisoners in England and Wales are not kept in solitary confinement. A prisoner may be removed from association where this appears desirable for the maintenance of good order or discipline, or is in the prisoner’s own interest. Prisoners in the adult prison estate may be separated in this way under the Governor’s authority for a maximum of 42 days. Segregation beyond this period must be authorised by a Prison Group Director, as an authority independent of the prison. The use of segregation is governed by Prison Service Order 1700.

The mental and physical health of prisoners removed from association is repeatedly assessed. Any prisoner segregated for over 30 days must have an individual mental health care plan in place. Segregated prisoners are managed by a multi-disciplinary team, which includes healthcare, mental health teams and psychology, overseen by a segregation review board. This board continually reviews both the physical and mental health of prisoners.
