Richard Dyson, 38, and Simon Midgley, 32, lost their lives in the blaze at Cameron House Hotel in December 2017.

A second preliminary hearing of a probe into the tragedy took place yesterday and another will take place on 22 June.

The purpose of a fatal accident inquiry is to determine the cause of death and to establish what lessons can be learned for the future in order to minimise the risk of future deaths in similar circumstances.

Last January, hotel operator Cameron House Resort (Loch Lomond) Ltd was fined £500,000, while night porter Christopher O’Malley, 36, of Renton, was handed a community payback order at Dumbarton Sheriff Court.

The fire started after Mr O’Malley placed ash and embers from a fireplace into a polythene bag and placed this inside a cupboard that contained combustible materials.

Cameron House Resort (Loch Lomond) Ltd admitted failing to take the necessary fire-safety measures and that it had breached health and safety rules.
