Bin Lorry Driver Tells Of Struggle
The driver of the bin lorry that killed six people days before Christmas has said he thinks of the victims "every minute of every day''.
Harry Clarke said he fell unconscious in the vehicle and cannot remember anything about the accident.
Erin McQuade, 18, and her grandparents Jack Sweeney, 68, and his 69-year-old wife Lorraine, all from Dumbarton, died in the incident in Glasgow's Queen Street and George Square on December 22.
Primary school teacher Stephenie Tait, 29, and tax worker Jacqueline Morton, 51, both from Glasgow, and Gillian Ewing, 52, from Edinburgh, were also killed when the truck mounted the pavement before crashing into the side of the Millennium Hotel in George Square.
In an interview with the Daily Record newspaper, Mr Clarke said "every day is a struggle'' but he wanted to reach out to the families of those who died.
Mr Clarke is undergoing tests for a heart condition and said he had no problems with his health before the crash.
"I never had anything wrong with my heart until that day,'' he told the Record. "I know going forward that won't help the families, but I just want all the families of injured or deceased victims to know I can't remember anything - I wish I could but I was unconscious.
"I have racked my brain to try to remember but I can't. I will never know what happened other than other people telling me what they saw. Every day is a struggle.''
He added: "I think of everyone every minute of every day.''
All of those injured in the crash have now been discharged from hospital, NHS Greater Glasgow and Clyde said last week.
The Crown Office has received the initial police report on the incident and will decide if there will be any criminal proceedings or if a fatal accident inquiry will be held.
A timescale for any further investigations will be outlined by the end of February.
