Steven Trayler says he is very grateful to the ambulance service

Steven Trayler said he was "enraged" that Mike Ferguson had been accused of breaking the law.

Mr Trayler, 44, of Church Village, south Wales, had a kidney transplant five years ago, and said he would not be alive if it was not for the ambulance service.

He said it was "the right thing to do" for organ transplant patients to support Mr Ferguson.

Mr Ferguson, was allegedly clocked by police doing 104mph as he delivered a liver from Leeds to Cambridge.

He could lose his licence or even if his job if convicted. But the case has caused outrage, with unions warning that lives could be lost if emergency drivers are not exempted from speeding laws.

Ambulance drivers transporting patients are exempted under the Road Traffic Regulations Act 1984 - as are police and fire engines - but transplant vehicles are not. 'Pathetic'

Mr Trayler, a former miner who has retired through ill health, told BBC Wales: "I was very ill for a long, long time and I didn't have a great deal of time left, so I had my kidney transplant, and I was very grateful for the ambulance men and the NHS."

He said: "I'm supporting the gentleman wholeheartedly.

"I just find it pathetic. This gentleman should be supported by all the organ transplant patients."

He added: "If it wasn't for the ambulance service I wouldn't be here."

Mr Ferguson, of West Yorkshire Metropolitan Ambulance Service, who has an unblemished record of over 30 years' service, was in an official vehicle with blue lights flashing when he was spotted by police on the A1 in Lincolnshire and Cambridgeshire.

The road has a 70mph limit and Mr Ferguson was charged with speeding by Lincolnshire Police.

Cambridgeshire Police are understood to have decided to take no action against him.

Mr Trayler said that even if Mr Ferguson had been doing 120 mph he should not have been prosecuted.

Solicitors for Mr Ferguson appeared at Grantham Magistrates Court on his behalf on Wednesday and indicated he would be pleading not guilty.

The case was adjourned until 11 June for a trial date to be fixed.
