A full court inquiry has been ordered into the fatal accident that killed six people, however it is understood no charges are to be brought against the driver.

Jack Sweeney, 68, who worked for the Ministry of Defence Guard Service (MGS) at RNAD Coulport, died alongside his wife Lorraine, 69, and their 18-year-old grand-daughter Erin McQuade.

Harry Clarke, 58, was behind the wheel of the Glasgow City Council refuse truck on December 22 last year, when it lost control and crashed near the city’s George Square.

The Crown has said it is not appropriate to speculate that driver suffering a heart attack caused bin lorry crash and that is something the Fatal Accident Inquiry will examine.

In a statement, the Crown Office said: “Crown Counsel have concluded that the driver of the lorry should not be prosecuted in respect of this tragic incident.

“Despite its catastrophic consequences there is no evidence to suggest that the driver’s conduct at the time amounted to a breach of the criminal law.

“There is no evidence to support a prosecution of Glasgow City Council in respect of any health and safety concerns breaches in health and safety law.

“Crown Counsel have decided that a fatal accident inquiry should be held into the causes of this tragedy to ensure that there can be a full public hearing of the facts of the case.” Mr Clarke has previously been quoted in press reports as saying he thinks about the victims 'every minute of every day’.

The fatal accident inquiry will aim to determine the cause of the crash and establish what lessons can be learned from the incident.

Victims Stephenie Tait, 29, Gillian Ewing, 52, and Jacqueline Morton, 51 also died. A further ten people were injured in the incident.
