Three dealers who distributed heroin and crack cocaine on Hounslow's streets have had their sentences slashed by top judges.

Mark Derek Baxter Clinton, of Bath Road, had his jail term cut from seven years to four years. Marc John Pert, also of Bath Road, saw his reduced from six and a half years to three years nine months, while Jose Paulo Valosa Rodrigues, of Green Lane, had his sentence cut from four and a half years to two and a half years.

All three had pleaded guilty to conspiracy to supply heroin and crack cocaine for drugs 'supremo' Jatinder Singh Grewal, 37, and his wife Amarjit Kaur Grewal, 35, from Slough, who both had their sentences slashed too.

The court heard that the Grewals were responsible for between s1,000 and s2,000 worth of Class A drugs going on to the streets of Hounslow every day.

They were arrested following a covert police operation in which officers made "test purchases" of drugs between December 2006 and February 2007.

When arrests were made, police found s16,000 worth of crack cocaine and heroin, as well as substantial amounts of cash.

Mrs Justice Rafferty, sitting with Sir Igor Judge and Mr Justice Grigson yesterday, said Amarjit Grewal administered the business, taking telephone calls from users and putting through their orders.

Her husband was the "supremo" who actually supplied the drugs to "loyal" dealers on the streets, including Clinton, 28, Pert, 24, and Rodrigues, 53.
