To ask the Secretary of State for Justice on how many occasions (a) workshops and (b) classrooms have been closed in each prison in England and Wales since 1 September 2013 due to staff shortages; and on how many occasions wings have been locked for (i) a half day, (ii) a full day and (iii) a lunch period for that reason since that date.

The information regarding the number of occasions on which (a) workshops and (b) classrooms have been closed in each prison in England and Wales since 1 September 2013 due to staff shortages; and on how many occasions wings have been locked for (i) a half day, (b) a full day and (c) a lunch period in that time and for that reason, is not collated centrally and is collected in different formats in each prison. The processes required to collect this data would incur disproportionate costs.
