Glasgow bin lorry crash driver Harry Clarke has "no memory" of the catastrophe which killed six people.

Clarke, 58, slumped unconscious at the wheel of the bin lorry as the disaster unfolded in Glasgow city centre.

Speaking to the Daily Record, he said: "I understand a lot of people want to know what happened that day. I wish I could tell you but I can't."

His lorry careered through crowds of Christmas shoppers before smashing in to a building. Among the dead were three members of the same family.

Clarke spent weeks in hospital after the crash receiving treatment for injuries and a previously undiagnosed heart condition.

He said he is in anguish about what happened and mourns the victims "every day".

"I just want all of the families of the injured and deceased 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 people telling me what they saw.

"I grieve for everyone involved in the accident. Every day is a struggle."

Clarke insisted he was not speaking out in a bid to win public sympathy, but because he wanted relatives of those who died to know his side of the story.

Victims were Erin McQuade, 18, and her grandparents Lorraine Sweeney, 69, and Jack Sweeney, 68. Also killed were Jacqueline Morton, 51, Stephenie Tait, 29, and Gillian Ewing, 52.
