A learner driver killed a great-grandmother in a horror smash while driving on the wrong side of the road.

Thomas Devlin, 26, overtook Vhaed Akhtar's car on the A76 Kilmarnock to Dumfries road and clipped the driver's mirror.

He continued - at speed - on the wrong side side of the road towards Donna Miller's car, which forced her to swerve to try and avoid him.

But Devlin hit Donna Miller's car which then hit the kerb and spun into the other side of the road and into the path of Mr Akthar.

His Ford Focus smacked into the boot and back of her vehicle, where her 68-year-old mother-in-law Isabella was sitting.

Devlin fled and Donna Miller and her husband Mark climbed out of the car, but Mrs Miller was trapped and pronounced dead at the scene.

A post-mortem revealed she had a number of injuries which could each have been fatal including a significant spinal cord injury, multiple rib fractures and a tear in the largest blood vessel in her body.

The findings indicated she would have died quickly on impact.

Devlin was later tracked down and told police he was the driver.

During his police interview he claimed his memory was not clear and accepted he was driving the Peugeot at the time.

He said he ran off because he was "scared" that he would not be insured without a qualified driver.

At the High Court in Glasgow on Wednesday, Devlin, from Auchinleck, Ayrshire pleaded guilty to causing the death of Mrs Miller by dangerous driving on the A76 near to Skerrington roundabout, Cumnock on March 24.

He also admitted a string of other driving charges including driving without 'L' plates or without insurance earlier that month, as well as not have a full licence or MOT on the day of the fatal crash, and failing to stop and provide details.

Judge Lord Burns deferred sentence until later this year for reports and remanded Devlin.
