Crime: Arrests

Mr. Boris Johnson
To ask the Secretary of State for Justice how many and what percentage of arrests in (a) England, (b) London and (c) each London borough led to criminal conviction in each year since 1997.

Maria Eagle
My Department collects aggregated data on number of arrests for recorded crime (notifiable offences) separately from record level data on all criminal convictions. This means that centrally we are unable to tell which arrests have led to a conviction.
