How the KGB recruited the Spanish Ambassador

"Russian historian Yuri Felshtinsky and former KGB Lieutenant Colonel Vladimir Popov claim in a new book, The KGB Plays Chess, that former IOC President [and Spain's ambassador to USSR], Juan Antonio Samaranch, was hired by the KGB in the late 1970s [...]

[...] Samaranch grew fond of Russian antiques, which he collected and shipped to his home in Spain. All antiques were closely monitored by the KGB; so the Spanish ambassador, a frequent buyer of valuable rarities, was taken note of. An agent from the KGB’s Second Main Directorate, which monitored the Spanish embassy, met with Samaranch and gently explained to him that his actions were subject to prosecution in accordance with the Russian Federation’s Criminal Code and were classified by Soviet law as the smuggling of contraband goods. According to Felshtinsky, Samaranch was offered a choice: he could either be compromised through the Soviet and foreign press detailing his activities, which would undoubtedly have put an end to his diplomatic career, or he could collaborate with the KGB as a secret agent."
