HC Deb 21 November 1986 vol 105 c372W
Mr. Cohen

asked the Secretary of State for the Home Department what evidence he has received since September 1985 about the efficacy of the Griess test; and what action he has taken as a result.

Mr. Douglas Hogg

The results of work performed by two independent forensic scientists have been considered as part of a re-appraisal of the Griess test conducted by the Home Office forensic science service. We are considering the findings in the context of our review of the case of the Birmingham pub bombings.
