High Quality Content by WIKIPEDIA articles! Frank Clifton Bossard (1912 – 2001) was a British Secret Intelligence Service agent who provided classified documents to the Soviet Union in the 1960s. MI6 recruited Bossard in 1945, stationing him in Bonn, Germany, with a large entertainment budget. When Bossard returned to London in 1961, he found his lifestyle unsustainable without the budget, and fell heavily into debt. After profiling him, the Soviet Union sent an agent to him, offering money in exchange for pictures of interest to the KGB and the Kremlin. A Soviet double agent known as "Top Hat" in actuality Dmitri Polyakov, revealed Bossard`s actions to MI5, who arrested Bossard on March 12, 1965. Bossard was convicted and sentenced to 21 years imprisonment. He was freed from prison in 1975 and returned to Yorkshire.
