Cocaine valued at £2.6m was found stashed in a secret compartment of a van being tracked by detectives.
Officers from the National Crime Agency monitored two transit vans as they made a trip to the Skelmersdale area from the south.
They swooped as the vehicles made their return journey, stopping the convoy as it travelled down the M1.
On searching the van, driven by Dean Melody, they found 33 vacuum-packed kilo blocks of cocaine in a false compartment in a locked chest.
The second van, driven by Arthur Boxall, contained an encrypted mobile phone.
Both were arrested on suspicion of conspiracy to supply class A drugs.
When tested, the cocaine was found to have a purity of between 60% and 95% and an estimated street value of more than £2.6m.
Melody pleaded guilty before the trial began but Boxall was found guilty by a jury at Kingston Crown Court last month.
They were both sentenced at Kingston Crown Court on Friday.
Melody, 46 and of High Street, Bishop’s Stortford, was jailed for 12 years.
Boxall, 52 and of Mawney Road, Romford, Essex was jailed for 22 years.
Following the sentencing Matt McMillan, NCA Operations Manager , said: “Disrupting the supply of class A drugs and the violence it fuels is a priority for the NCA and our partners.
"Drugs trafficking is a major source of revenue for organised crime groups, many of whom are involved in other criminality, and profits from illegal drugs are used to fund other criminal operations.
“The comprehensive investigation conducted by the Organised Crime Partnership has successfully disrupted an organised criminal network involved in the large scale supply of class A drugs.
"We have ensured that the 33 kilos of cocaine that Boxall and Melody were found with will not get onto the streets of the UK.”
