, London Finding his desk job unsatisfying, Tomlinson joined the Territorial Army in September 1989 and, after passing selection, served as a reservist with the
SAS in the
Artists Rifles, and then
23 SAS, qualifying as a military
parachutist and
radio operator. He represented Britain in the 1990
Camel Trophy, competing in
Siberia, and crossed the
Sahara desert solo on a motorcycle. He enjoyed the experience, subsequently applied to join MI6, and officially joined the Service on 23 September 1991. He completed his training with MI6 and claims he was the best recruit on his course, being awarded the rarely given "Box 1" attribute by his instructing officers including
Nicholas Langman. Tomlinson worked in the "SOV/OPS" department, operating during the ending phases of the
Cold War against the
Soviet Union. He was posted to a diplomatic role in
Moscow, and was one of the agents responsible for the retrieval of the
Mitrokhin Archive in 1992. Whilst working there, it was discovered that the
Conservative Party had been receiving donations from Serbian supporters. From 1994 to 1995, Tomlinson worked in the operational
counter-proliferation department. His first posting in this capacity was to work as an undercover agent against
Iran, where he succeeded in penetrating the
Iranian Intelligence Service. He posed as a British businessman, and infiltrated a network of arms dealers that included
Nahum Manbar. MI6 dismissed him on 22 May 1995 as he came to the end of his extended
probationary period. Tomlinson's probationary period had been extended over the standard six-month duration due to his senior line manager's doubts about his personality. Tomlinson claimed that he had become suicidally depressed following the death of his long-term girlfriend from cancer and that he had been suffering from
post-traumatic stress after witnessing violence against a civilian during the
siege of Sarajevo, and that MI6 had been ill-equipped to handle his condition. MI6 argued that he was dismissed for "not being a team player, lacking motivation and having a short-term interest in the service", but later conceded that he had experienced a "
personality clash" with his senior
line manager. Another reason given for his dismissal was for "going on frolics on his own". Tomlinson argued that his supervisors had unfairly disregarded his personal circumstances. Since 2000, employees of MI6 have had the same employment rights as other British citizens, including written contracts and access to employment tribunals. However, MI6 refused to allow these procedures to be applied retroactively to Tomlinson's case. MI6 have not succeeded in obtaining another PII certificate since the Tomlinson case. ==
