The Security Service's historic files on Horst KOPKOW were made available to the public at The National Archives in March 2004 (reference numbers KV2/1500 and KV2/1501). KOPKOW also appears in a report on a file at The National Archives relating to the Gestapo that was made available in February 2005 (reference number KV3/109). None of the files held in The National Archives on Horst KOPKOW are closed. Any redactions made to these files have been made for reasons of national security. The Government is committed to releasing historical files to the National Archives where it is appropriate to do so.
