A man suspected of the racist murder of Stephen Lawrence has been detained for nine years for drug-related conspiracy.
42-year-old Jamie Acourt pleaded guilty to the conspiracy to deliver cannabis resin in northeast England.
It is the last conviction in an investigation by the Political Command of the Metropolitan Police, in which seven men were charged with a complex and highly organized drug network.
Acourt previously denied the conspiracy to deliver a Class B drug between January 2014 and February 2016, but changed his request when the prosecutor's office opened its case.
He then agreed to plead guilty to the plot only from January 2014 to May 2015.
Acourt's brother, Neil Acourt, has been imprisoned for more than six years because of his role in the system.
Jamie Acourt from Eltham in southeast London lived two years fleeing Spain and lived under the name of Simon Alfonzo until he was arrested in May when he left a gym in Barcelona.
Prosecutors said the brothers were ringleaders who called on family members to move around 3 million pounds of drugs across the country.
Judge Peter Lodder said, "That you played a leading role is out of the question.
"I was asked to remember that you retreated from the plot following the arrest of (Darren) Woods and that the conspiracy continued without appointing a new leader, suggesting that your role was not critical."
He said the system was well established before it failed.
Both Acourts were arrested in 1993 after black teenager Stephen Lawrence hit, but always denied any involvement.
The prosecution in the case of Neil Acourt said that the system involved dozens of 600-mile tours from London to South Shields to take drugs and bring back money.
The prosecution said Jamie Acourt was involved in the supply of 500 kilograms of cannabis resin worth £ 2.2 million.
Jamie Acourts Defense Attorney said, "It is a mitigating factor he has withdrawn from the plot, though one of the co-conspirators may have recently been arrested."
Seven men have since been convicted, including Lee Birks, 57, the stepfather of Jamie Acourts's partner, and Neil Acourts 65-year-old father-in-law, Jack Vose.
The case against Darren Woods was dismissed.
