Furious West Belfast UDA chiefs are blaming the UVF over a series of police raids which have decimated its money-spinning drugs rackets.
The latest row between the groups comes after major drugs baron Dee Jenkins, who detectives believe pays the UDA protection cash, appeared in court charged with a range of offences.
These include supplying cocaine and cannabis, and possessing criminal property.
The 40-year-old was arrested last month following Paramilitary Crime Taskforce raids that the PSNI said were directed at the West Belfast UDA.
The move against him came after local women staged an anti-drugs protest near his home on Hopewell Avenue.
Jenkins, who served a prison sentence for running a cannabis factory, has since accused UVF leaders of "touting" on him.
His court appearance last Wednesday came after UDA C Company chief Denis Cunningham caved into pressure from UVF leaders on the Shankill and told its members to stop selling cocaine and cannabis. But the order has been laughed at by UDA dealers who make a fortune peddling the poison. Among those openly ignoring Cunningham's demand is UDA extortionist Dee Coleman, who was freed from prison last month having been convicted of membership of the terror gang.
Veteran C Company member and convicted killer Mo Courtney has also been dismissive of the order.
Both see Cunningham as a figure of fun - he was jailed a decade ago for reading out a terror statement while wearing his distinctive glasses over his balaclava - and have been openly ignoring his wishes. "Denis has said he wants to put a stop to the drug dealing in the Shankill estate, but that won't happen so long as Dee Coleman is about, and Mo to a certain extent," a UDA source said.
"They have no respect for him, or his second-in-command who has a cheek to say he opposes drug dealing when he's before the courts facing a charge of possessing drugs."
The UDA's anti-drugs order came after the Shankill UVF pledged to oppose criminality in recent meetings with senior civil servants. In return they expect £5m of funding from the government's £50m Fresh Start package set up to help end paramilitarism.
Earlier this month the UVF ordered two drug dealers, who had been paying protection cash to the UDA, out of Ainsworth Avenue and the Glencairn estate.
Police have also been seen calling to the Shankill Road offices of the UVF-backed Action for Community Transition (ACT) Initiative to retrieve drugs seized by the charity, which received £290,000 of public funding last year.
In a separate anti-drugs operation the PSNI last month charged two members of the same family - Denise Chambers (53) and Samuel Chambers (19) - both with an address on Forthriver Road, of dealing cocaine and possessing a stun-gun. There is no suggestion the pair are connected to the UDA.
Our loyalist source added: "C Company was the only UDA unit on the Shankill that wasn't taking orders from the UVF, and that's because there is still a lot of bad blood between both groups stretching back to the loyalist feud. The attitude was sure UVF leaders are hypocrites because they take protection money from shopkeepers on the Shankill and make a fortune selling illegal cigarettes.
"But then, all of a sudden Denis (Cunningham) said the drug dealing has to stop. Well, he can say what he likes, but no one will listen especially Dee Coleman and Mo Courtney. They've no respect for him and Denis knows this."
Police chiefs estimate the West Belfast UDA makes in excess of £2million annually from the drugs trade. Its continued involvement in serious crime will feature in an assessment of paramilitarism in Northern Ireland to be published later this month by the Independent Reporting Commission. The unit is led by veteran UDA figures Jim Spence and Matt Kincaid, who say they have no connection to crime.
Meanwhile, UVF bosses in Larne have been accused of demanding a massive 'fine' from a drug dealer recently caught with £100,000 of cocaine and ecstasy, The criminal, who was freed on High Court bail, was visited at his home on the outskirts of the Co Antrim seaside town and ordered to pay the terror gang £50,000. He was told it was for drug dealing in the area.
