To ask the Secretary of State for Justice, what estimate she has made of the cost to the public purse of pest control at HMP Wandsworth in the last 12 months.

HMP Wandsworth pays £16,238 per annum for a contracted weekly pest control service. The cost of additional pest control work during the last 12 months totals £99,900.92. This work is being carried out as part of our wider efforts to improve living conditions at the prison, which also includes additional specialist staff, to ensure immediate action is being taken.
