To ask the Secretary of State for Justice how many people convicted in each of the last 10 years had never previously been convicted, broken down by police force area. 
The following table shows figures taken from the Ministry of Justice's extract from the Police 22 Oct 2008 : Column 466W
National Computer (PNC). It shows the number of people convicted of indictable offences in each year since 2000 who at the time of their conviction had no previous convictions recorded on the PNC.

These figures have been derived from the police's administrative I.T. system, which, as with any large scale recording system, is subject to possible errors with data entry and processing.
