The ringleaders of a Liverpool-based gang that supplied tens of millions of pounds of cocaine and heroin to the streets of Glasgow have been jailed.
Father and son Christopher Welsh Snr, 55, of Regal Walk and Christopher Welsh Jnr, 34, of Payley Close, led the plot, Liverpool Crown Court heard.
A further seven members of the gang were jailed, with 21 more due to be sentenced in the next few days.
They were responsible for "flooding" Glasgow with drugs, police said.
Titan, which is the regional organised crime unit in north-west England, said its intelligence suggested there were at least 111 trips to Scotland.
It estimates the drugs trafficked in those journeys had a total street value of between £100m to £200m.
Det Supt Jason Hudson, head of operations for Titan, said the gang was at the very top of the organised crime network.
He added: "This gang were responsible for flooding the streets of Glasgow with incredibly dangerous and damaging Class A drugs, profiting from other people's misery in the process.
"The top tier of this gang masterminded a massive criminal enterprise which helped them live the kind of comfortable lives most people would envy.
"They thought they were above the law. I am pleased to say that there will be no more fancy holidays abroad for these individuals."
Welsh Snr was jailed for 15 years, four months, with his son receiving 16 years, eight months.
Police said Welsh Jnr's lavish lifestyle included paying £57,000 in cash to take 40 relatives and friends to his stag do and wedding in Mexico.

- Mark Shield, 45, of no fixed address, who was jailed for 14 years, eight months
