Question to the Home Office:

To ask the Secretary of State for the Home Department, what the crime detection rate was in (a) Bury St Edmunds constituency, (b) Suffolk and (c) England and Wales in each year since 2010.

There was a significant change from the former detections framework to the new outcomes framework in April 2013. The new outcomes framework includes a broader range of "outcomes" for crimes dealt with by the police. This provides greater transparency on how crimes are resolved when compared with the former detections framework which only covered a subset of the new outcomes and, therefore, of the ways crimes are "resolved".
Information on the new outcomes framework and data for England and Wales were published by the Home Office in its "Crime Outcomes in England and Wales 2013/14" bulletin, alongside the number of outcomes in each police force area.

While statistics published from 2013/14 onward focus on the new outcomes framework rather than detections, it is technically possible to calculate the former detection rates. Figures for Suffolk Police and England and Wales are shown in the table provided. It is not possible to provide data for Bury St Edmunds constituency as outcomes data are collected at police force area level.
