To ask the Secretary of State for Justice what the ratio of prison officers to inmates by gender was in each (a) prison establishment and (b) category of prison in England and Wales in each of the last five years.

Information on the ratio of prisoners to prison officers has been provided previously to Sadiq Khan. I refer my hon. Friend to the reply given on 4 March 2014, Hansard, column 805W.

It is not possible to calculate a meaningful ratio of prisoners to staff based on gender. Any officer to prisoner ratio must take account of all available staffing, of either gender, in order to realistically represent the level of staffing.
