LONDON, Jan.6 (Xinhuanet) -- Thirty-four people have been jailed for a total of more than 300 years after British police smashed the country's biggest drugs and money-laundering operation, snatching a total of 3.5 million in cash and 645 kilograms of cocaine in the process.

   Maria Cannes Gomez, 36, who is the final defendant, was convicted at a London court following a four-year probe, Sky news reported on Friday.

   Gomez pleaded guilty to laundering 750,000 pounds (about 1.35 million U.S. dollars) in cash and forging a passport and will be sentenced in March.

   She is the last of the defendants, mainly from Colombia, to be convicted in Britain following operations by the Metropolitan Police and the National Crime Squad.

   Colombian police helped their British counterparts dismantle the highly-organized cocaine importation and money-laundering ring.

   Former asylum seekers Jesus Anibal Ruiz-Henao, 45, and his brother-in-law Mario Tascon, 32, who headed the network, are known to be serving jail sentences of 19 and 17 years.

   The other defendants -- 25 from Colombia, three from Britain, one from Canada, four from Spain and one from Panama -- were convicted at earlier hearings.

   The gang supplied drugs to every major British city, and after their arrest the price of cocaine on the streets shot up by 50 percent.

   The ring was believed to be Britain's largest drug distribution network, employing at least 50 people. Enditem
