A PATIENT who was given a fatal overdose by an overseas locum was unlawfully killed, a coroner ruled today.

The death of David Gray amounted to gross negligence and manslaughter, said Cambridgeshire North and East Coroner William Morris.

In a damning conclusion to the 10-day inquest, the coroner described Dr Daniel Ubani, who treated Mr Gray, as "incompetent and not of an acceptable standard".

He also criticised out-of-hours care saying: "Weaknesses remain in the system.'

Mr Gray, 70, died after he was injected with 100mg of diamorphine - 10 times the recommended daily dose.

He was suffering from renal colic when he was treated by Dr Daniel Ubani at his home in Manea, Cambridgeshire on February 16, 2008.

The inquest heard that Dr Ubani was working on his first out-of-hours shift in Britain for Take Care Now - which until recently provided out of hours care for Suffolk - and had only arrived in the country the day before.

The case highlighted concerns about the standard of out-of-hours GP care offered to patients.
