Two drug runners involved in a £5million cocaine ring have had their bids to reduce their prison terms rejected by top judges.
Simon Woodcock, of Tudor Road, Hayes, was part of a gang that transported large quantities of high purity cocaine and set up an industrial drug cutting factory.
He was said to have played less of a role than accomplice David Walton, of Kings Close, Surbiton.
Both were charged with conspiracy to supply cocaine.
Woodcock, 53, denied the offence but was convicted after a trial, while Walton, 44, pleaded guilty.
Both were sentenced to nine years in jail at Kingston Crown Court in October last year.
The Court of Appeal heard on Thursday last week that police recorded drug-related phone conversations between the gang's ringleader, Matthew Lawless, 35, of Egham, and Walton about significant amounts of drugs and cash in November 2012.
Walton and Woodcock were caught by surveilling police transporting high-purity cocaine and testing an re-packaging equipment respectively, to a property in Staines.
At their appeal, both men's legal teams argued that their roles in the operation had been overstated, but these arguments were rejected.
"We conclude that nine years was, although stern, neither wrong in principle nor manifestly excessive. For that reason, this appeal against sentence is dismissed," Mr Justice Coulson concluded.
