§ Mr. Mitchell
To ask the Secretary of State for the Home Department if he will make a statement on the effects which implementation of EC directives 80/181 and 89/617 has had on the ability of the police to identify suspects. 
§ Mr. Michael
The implementation of these directives represented the final stage of the process of replacing imperial units with metric units as the primary system of measurement. We have no evidence that the adoption of metric units has affected the ability of the police to identify suspects.
