A FORMER Ministry of Defence stores employee has denied being a drug dealer and claimed he wouldn't know how to be one.

Roy Ernest Colsell, 64, alleged from the witness box in court that he had no knowledge of drugs found in the car in which he was a passenger in May 2013 or in the house where both he and co-defendant Syed Juhel Miah, 48, live.

However, Miah claims letters Colsell wrote is a confession to drug offences.

Clinical psychologist Eric Wright said that, after carrying out tests, he assessed Colsell as having an IQ of 75 and of being abnormally suggestible and very likely to defer to those he saw as being in an authoritative position.

Both Miah and Colsell, of Tennant Road, Acomb, deny six charges of possessing drugs with intent to supply in May 2013. Miah denies a seventh charge of possessing cannabis with intent to supply in May 2015. Colsell worked for the MoD for 18 years.

The jury has heard both men were in an orange Toyota on Piccadilly, York, on May 26, 2013, in which police found cocaine, Ecstasy and cannabis. In his pocket, Colsell had the key to a hired Toyota, parked on Kingsland Terrace, off Leeman Road, where officers found cannabis. They also found cannabis and Ecstasy in their home.

Giving evidence, Colsell alleged that he had never seen or known anything about drugs in either the car or in the house.

"Have you supplied them (drugs) to anyone?" his barrister Eleanor Fry asked him.

"No, I wouldn't know how to do that," he replied.

He claimed he didn't know how to drive and had lost his licence in 2004. He claimed Miah had given him the key to the hired car to look after.

Colsell also claimed on the day both men were arrested on Piccadilly, that they had been shopping at Morrison's Foss Island Road when a man asked them to take him to Piccadilly. The man had given Miah a pouch which he had then in turn given to Colsell which he had put in his jacket pocket.

He alleged the same man had asked for the key to the hired Toyota.

Mr Wright alleged that Colsell's IQ was "borderline low" and put him in the bottom five per cent of the general population.
