A father and son commandeered a disabled man's car for a dial-a-deal drug service.

Dennis Davies, 55, was employed as a driver for the disabled man but also used the vehicle to make deliveries of cocaine and cannabis across Brighton and Hove.

His son Jamie, 31, took orders over the phone.

Their two-year operation was smashed by undercover police who followed Davies senior and captured him on camera carrying out deals on doorsteps across the city.

Detectives from the National Crime Squad also hid a recording device in the duo's safe house to monitor their conversations.

When the disabled man's car was searched, traces of drugs were discovered throughout the interior.

The investigating officers built up a lengthy dossier on their activities before arresting them in March 2001.

They estimate the pair had sold drugs with a street value of up to £90,000 in the previous two years.

Davies senior, of Nettleton Court, in Upper Hollingdean Road, Brighton, and his son, of Borough Street, Brighton, were both told at Chichester Crown Court yesterday they faced jail after admitting conspiracy to supply drugs.

John Bevan QC, prosecuting, said: "Dennis was the delivery man and Jamie was the brains of the outfit.

"Jamie didn't expose himself to the risks and it was left to his father to do the leg work."

Both pleaded guilty to conspiracy to supply cocaine, conspiracy to supply herbal cannabis and conspiracy to supply cannabis resin.

All the offences took place between March 6 and 30, 2001.

The pair are due to be sentenced on October 23 after reports have been prepared.

Both were remanded in custody.
