A motorist involved in a fatal crash while on the wrong side of a dual carriageway had possibly suffered a hypoglycemic event, a pre-inquest hearing was told.

Acting senior coroner for North West Wales, Kate Sutherland, said the Betsi Cadwaladr University Health Board should remain an “interested party” at the full inquest into the death of Christopher Paul Jones, aged 40, of David Street, Penmaenmawr, on the A55 at Talybont, Bangor, in February 2018.

The hearing at Caernarfon heard extensive investigations had been made into whether there was any defect with a diabetic pump used by motorist John Keith Williams.

The BCUHB argued there was no indication any act by an employee contributed to the tragedy.

But Matthew Kerruish-Jones, representing Mr Williams’ insurer, at the third pre-inquest hearing into the death, said it was suggested a nurse had pre-programmed the insulin pump and there had been “mismanagement” of his condition.

The coroner said the full inquest would be listed for two days when evidence will be given by witnesses.

Police said a Nissan was driving the wrong way and collided with the Hyundai Mr Jones was driving.

His family, who weren’t at the pre-inquest hearing, described him as "thoughtful, kind, generous and funny."

In a tribute, issued via police just after his death, they added: "It goes without saying that Paul's family are devastated by his sudden loss and he will be missed by all."
