To ask the Secretary of State for Justice pursuant to the answer to the hon. Member for Chesterfield of 7 January 2010, Official Report, column 546W, on prison accommodation, how many places were not included in the certified normal accommodation of the prison estate in each of the last three years. (317144)

This information could be obtained only at disproportionate cost as it would require a manual trawl of the changes to every establishment's certified normal accommodation over the last three years.
