The council accepted liability for the 2014 tragedy that saw a lorry lose control on Queen Street after driver Harry Clarke blacked out. Six people were killed before the vehicle crashed into Queen Street Station at the Millennium Hotel.

But the council’s insurers want First Glasgow, Mr Clarke’s previous employer, to share liability. He was employed with First Bus for two years before he took the job with the council.

It was discovered that he “deliberately concealed” medical information from the Driver & Vehicle Licensing Agency (DVLA) and supplied false information on a medical assessment form with the council.

Had First Bus provided the council with an accurate medical history, he would not have been employed as a bin lorry driver, the council’s lawyers argue.

Andrew Jarvis, managing director for First Glasgow, said: “Mr Clarke was a driver for First Glasgow between October 2008 and December 2010. 

“Our thoughts remain with those affected by the tragic events of December 22, 2014. 

“We will vigorously defend our position and question the rationale of Glasgow City Council’s decision to invest significant funds, which could be directed elsewhere, in unwarranted legal proceedings.”

A council spokesman said: “This is a matter for our insurers. It would not be appropriate to comment further at this time.”
