The Irish, British and Dutch ganglands are crazily interconnected. You have underworld figures from Dublin, Liverpool, Glasgow, London, Essex, Amsterdam, Rotterdam...or even North Morocco, Curaçao as well as trailer parks in West Brabant, Limburg, South Holland...forming huge reticular networks. Crime groups from these locations really play a disproportionate role in the European cocaine and synthetic drug trade.
Also the IRA, Turks-Kurds and Lebanese.
The IRA definitely. Even the British groups from the Southeast have connections to them.
The Turks and Kurds do dabble in cocaine, but it isn't really their drug of choice. The Kurds in North London for instance concentrate almost exclusively on heroin. Over here in Belgian Limburg occasionally there is a cocaine shipment destined for a Turkish group, but in general it's mostly Italians involved in this stuff. I'd say the Turks and Turkish Kurds aren't really "the" major players in the cocaine business.
The Lebanese are involved in cocaine as well, among other stuff such as heroin. The thing with the Lebanese is that they're incredibly concentrated in the big German cities and mostly stick to their local environment. I don't think they're major importers of cocaine or other narcotics, even though they do deal in that stuff as well. Organized blue-collar crimes such as extortion, loan-sharking, organized robbery and burglary seem to be more their bread and butter.
