A damning report into the fire which destroyed Glasgow School of Art for the second time in four years will call for a full public inquiry, STV News has learned.

MSPs on the Scottish Parliament's culture committee have been investigating the circumstances surrounding the blaze at the Mackintosh building last June.

Their findings will be published on Friday, however in sections seen by STV News they express grave doubts about the school of art's management.

Committee members also criticise evidence provided by those involved in rebuilding work following the previous blaze in 2014.

Ultimately, the MSPs feel they have taken their investigation as far as they can, and believe a full public inquiry is necessary.

They argue that the massive cost of rebuilding the art school justifies an inquiry similar to those held into the construction of the Scottish Parliament and Edinburgh trams network.

The second fire broke out at the Mackintosh Building on Sauchiehall Street late on Friday, June 15 while it was undergoing a £35m restoration.

Nearby buildings, including nightclubs, were evacuated, while residents were forced to flee their homes.

No-one was injured, but more than 150 firefighters remained at the scene overnight as the flames spread to nearby buildings, including the historic ABC nightclub, which is now set to be demolished.

It came four years after the art school previously caught fire - a blaze which caused significant damage to the west wing, including the loss of the celebrated Mackintosh Library.

That fire began in the degree show exhibition when artwork made from foam was set alight by a hot projector.

A full-scale model of part of the library was later built to test if the original materials and techniques from Mackintosh's 19th-century design could be used in its reconstruction.

Work had been due to be completed in February this year.
