A court hearing on whether or not a private prosecution can be launched against Glasgow bin lorry crash driver Harry Clarke is under way.

Mr Clarke, 59, was behind the wheel of the vehicle when it went out of control in Queen Street on December 22, 2014, killing six people.

Relatives of crash victims Jack and Lorraine Sweeney, aged 68 and 69, and their granddaughter Erin McQuade, 18, are pursuing the court bid.

Stephenie Tait, 29, Jacqueline Morton, 51, and Gillian Ewing, 52, also died in the incident.

At the two-day hearing at the Court of Session in Edinburgh, the three judges are also considering a similar application to prosecute William Payne, lodged by the families of students Mhairi Convy, 18, and Laura Stewart, 20, who were knocked down and killed in Glasgow in 2010.

Details of the hearing cannot be reported for legal reasons.

It is being held before the second highest judge in Scotland, the Lord Justice Clerk Lady Dorian, as well as Lord Menzies and Lord Drummond Young.

In each case, the Crown Office decided not to prosecute the drivers involved.
