About Michael John Smith
Born 1948. Michael John Smith is a British spy.
Michael John Smith (born on 22 September 1948) was convicted of spying in the UK.
In 1992, Smith was arrested, accused of spying for the KGB, and charged with four offences under sections 1(1)(b) and (c) of the UK Official Secrets Act 1911. Smith was convicted on the three section 1(1)(c) charges relating to "communicating material to another for a purpose prejudicial to the safety or interests of the State". He was sentenced to 25 years in prison,
Christopher Andrew, in his history of the KGB, described Smith as "probably the most important British Line X agent since the retirement of (Melita) Norwood".
Education Between 1960 and 1967, Smith attended Ockendon Courts County Secondary Modern School in Essex and gained nine GCE 'O' levels and four 'A' levels. He went on to the University of Surrey where he graduated in 1971 with a degree in electronic and electrical engineering.
Early politics Smith joined the Communist Party of Great Britain
Employment After graduating, Smith found employment for a short time as a trainee assistant electronic engineer at a small engineering company. In April 1972, he joined Rediffusion in Chessington as a junior engineer.
In July 1976, he started work as a test engineer in the quality assurance department of Thorn EMI Defence Electronics at Feltham, Middlesex. who befriended him at a union meeting in 1975 In court, the prosecution offered no evidence to support this allegation.
Oshchenko defected in July 1992 and provided information that is said to have confirmed suspicions that Smith had provided information on the XN-715 radar fuse
Arrest By the time of Oshchenko's defection, Smith was no longer working for a defence contractor. The Security Service, MI5, gave him the code name Parellic and placed him under surveillance. Given the information provided by Oshchenko after his defection it was decided to arrest Smith as soon as possible. In August 1992, a member of the Security Service telephoned him pretending to be a friend of Oshchenko and suggested that they should meet.
Damage assessment The report of the Security Commission dated July 1995, prepared after an inquiry into the case, stated that,
"The material known to have been obtained by Smith during his time at GEC which led to the charges and his conviction under the Official Secrets Act, was a mixed bag. Some was already in the public domain and some was of value more for its commercial than for its military potential. But a number of documents contained more sensitive material, relating to weapons systems. The potential damage to the UK overall including the Rapier is assessed as considerable. In the case of the other current weapon system, the detailed information contained in the document which should have been classified SECRET would have enabled an intelligent enemy to deduce operating parameters which would have allowed counter-measures to be developed. The potential damage to the national interest in the case of that weapons system is assessed as serious."
Follow-ups On 10 January 2006, Andrew Mackinlay MP asked in Parliament for clarification as to which weapon system the most serious document in the prosecution was linked. Smith alleges that this document had nothing to do with ALARM, as alleged in his trial.
