A former detective who was "pivotal" to the success of a plot to smuggle cocaine worth £200m into the Republic of Ireland has been jailed for 22 years.
Michael Daly, who is already serving eight years behind bars for a similar conspiracy, was "driven by greed", police said.
Judge Henry Blacksell QC sentenced Daly when he appeared at Blackfriars Crown Court in London.
Daly's co-conspirator, former firefighter Alan Wells, was jailed for 14 years.
Daly used skills and knowledge gained as a Metropolitan Police drug squad detective to try to smuggle 62 bales - more than 1,500kg (3,300lb) - of cocaine into southern Ireland.
But Daly and the gang were foiled when their boat ran out of fuel in rough seas and was shipwrecked off the Irish coast in July 2007.
Daly, 49, and Wells, 57, of Blenheim Road, Sidcup, south east London, admitted conspiracy to supply cocaine.
'Pivotal'
Daly was pivotal to the plot's success and was due to share in the huge profits, police said.
He was in overall charge of the logistics and also possessed local knowledge to plan the operation as his family lived on the south coast of Ireland.
Wells admitted being paid £100,000 for his role in helping Daly to organise the logistics.
Detective Inspector Grant Johnson, from the Met's Serious and Organised Crime Command, said: "Driven by greed, their activities would no doubt have netted them large sums of money had it not been for law enforcement agencies, particularly our Irish colleagues, working in partnership to identify and convict those concerned.
"Daly, one of the key ringleaders, was an ex-Met detective, who, once leaving the service, clearly abused the knowledge and skills he gained as a police officer for criminal gain."
He added:"We hope this shows that, no matter who you are, or what job you do, if you commit the crime, the consequences will follow."
