regularly couriered hash to London on his behalf via ordinary airline flights, arranging for the pot to be concealed in body harnesses strapped to those paid to act as drug mules. It was by such means that Plinston's supply was smuggled until Hraoui introduced him to Mohammed Durrani in 1969. Durrani knew some Pakistani government officials who were prepared to exploit their diplomatic immunity to smuggle hash. By this means Durrani's diplomats were able to get drugs into mainland Europe but not the UK. The biggest hurdle for dope smugglers was getting their gear into Europe; transporting it around the continent was viewed as considerably less risky. Nonetheless Plinston and Geoff Thompson were busted in Lorrach in 1970, as they ferried dope in a car from Switzerland across the West Germany border. This is the famous seizure that gave Howard Marks his break into the major league of the pot trade. After being sent by Mandy Plinston to sort things out in Germany and then reporting back to various Middle Eastern connections about what had and hadn't been compromised, Marks took over portions of Plinston's business while his friends Plinston and Thompson did time in jail. 
Bizarrely, John Pearson in his tomes on sixties British gangsters the Kray Twins writes about a man called Alan Bruce Cooper,  who it is claimed was working reluctantly and under threat of imprisonment for the American Bureau of Narcotics and Dangerous Drugs. Among other things, the American authorities are said to have known that Cooper had been manufacturing LSD and trafficking in this drug. Supposedly, it was decided that Cooper should entice Ronnie and Reggie Kray into committing crimes for which they could be convicted because the authorities in the USA were concerned about their connections to the American Mafia. Regardless of exactly what role various intelligence agencies did or did not have in controlling Cooper, he was a major player in the events that culminated in the conviction of the Kray twins for murder. In The Profession of Violence, Pearson provides the following details about a few of Cooper’s schemes:
Cooper had the big ideas that Ronnie needed and seemed as thrilled as Ronnie by them all. They often talked about narcotics. Cooper had European contacts and clearly knew the market. This was
In 1965 Abbot had to flee the Balearic Islands because he was stopped on the Spanish border in a van filled with pot, which he’d driven overland from Istanbul. Seeing a customs officer prising open the panelling behind which drugs were concealed, Abbot with his passport held aloft, wandered off pretending he was looking for an office at which to present his papers. He got up onto a hillside from where he could observe what
I can't identify with any certainty the first major drug smuggler my mother - Julia Callan- Thompson - befriended, but one she met early on was an Irish exile who I'll call Dave Abbot (this is not his real name). My mother met Abbot in Henekey's pub in Portobello Road. She wanted to go to Spain and Abbot had lived for a time in Ibiza, and so they decided to head out there together. After a vacation on the Balearic Islands, Abbot, my mother and their traveling companions returned to London. Abbot craved sunshine and before long had returned full-time to Ibiza. My mother would head out to Spain in the summer and hang with Abbot's set on Ibiza, but she was based in London until the end of 1966 when she temporarily relocated to Paris.
