Jack Straw (then Home Secretary) stated to the British Parliament in 1999: "In 1992, after Mr. Mitrokhin had approached the UK for help, our Secret Intelligence Service made arrangements to bring Mr. Mitrokhin and his family to this country, together with his archive. As there were no original KGB documents or copies of original documents, the material itself was of no direct evidential value, but it was of huge value for intelligence and investigative purposes. Thousands of leads from Mr. Mitrokhin's material have been followed up worldwide. As a result, our intelligence and security agencies, in co-operation with allied Governments, have been able to put a stop to many security threats. Many unsolved investigations have been closed; many earlier suspicions confirmed; and some names and reputations have been cleared. Our intelligence and security agencies have assessed the value of Mr. Mitrokhin's material world wide as immense."
