THE families of two women killed by a diabetic driver who blacked out behind the wheel are calling for a change in the law to prevent similar tragedies.

Enid Mills, 72, of Abbey Close, Pinner, was jailed for 18 months at Harrow Crown Court on Friday, December 17 on two counts of causing death by dangerous driving.

Helen Brady, 70, and close friend Alice Cullen, 72, (pictured) who both lived in Sudbury, were hit by Mills's car after she suffered a hypoglycaemic episode at the wheel.

Mrs Brady's son, Aiden, said links should be set up between medical staff and the DVLA (Driver and Vehicle Licensing Agency), so that an unstable patient could have their licence revoked immediately on the advice of a doctor.

He said: "The sad thing about this case is the doctors told her [Mills] not to drive. Health workers told her not to drive. But the onus was on her to tell the DVLA.

"We want to highlight this because we would hate another family to go through what we have."

Mr Brady said his mother, of St Andrew's Avenue, and Ms Cullen, of Elms Park Avenue, had been friends for 40 years and their children had grown up together.

Mills denied causing the deaths but was found guilty at the end of her trial in September. Sentencing was postponed because she was being treated at Northwick Park Hospital for a mental illness suffered since the fatal road crash.

Judge Alan Greenwood told Mills: "You suffer with diabetes and we sympathise with you for it, but the problem is that it caused you to have hypoglycaemic episodes in which you lost consciousness and it was obvious you were not fit to drive.

"Your diabetes was unstable and poorly controlled. The consequences of your driving that day, which you must live with for the rest of your life, is that two lives were lost.

"I know you are remorseful but it would have been easier to take account of had you pleaded guilty."
