A teenager's dangerous driving led to the death of a friend after he lost control of his car.

Aaron Murphy, who was 18 at the time, overtook a line of traffic in unsafe conditions before his Seat Ibiza mounted a verge, hit a sign and rolled into a field.

His front seat passenger and former schoolmate Dale Whillans, also 18, suffered fatal injuries in the crash on a road in the Borders.

Murphy, now 19, of Braid Road, Hawick, admitted causing the death of Mr Whillans by driving dangerously on the A698 Hawick to Jedburgh road on April 6, 2015.

The court heard he drove at excessive speed and crossed on to the other side of the road when it was unsafe, losing control of the vehicle.

Advocate depute Keith O'Mahony told the High Court in Edinburgh that Murphy had overtaken several vehicles at a location where it was unsafe to do so. Witnesses estimated his speed at the time as more than 70mph.

After the crash, an off-duty surgeon and paramedic tried to give aid to Mr Whillans but he did not survive his injuries.

Murphy's defence counsel Ronnie Renucci told the court: "I am instructed on behalf of Aaron Murphy to apologise on his behalf at the first public opportunity that he has had."

Judge Lady Wolffe deferred sentence on Murphy until next month for the preparation of a background report and agreed to continue his bail. Murphy was banned from driving in the interim.
