Hundreds of privately owned flats in Glasgow contain combustible cladding materials, STV News understands.

Glasgow City Council leader Susan Aitken has promised to begin informing residents by the end of next week.

Around a dozen blocks are thought to have a substantial amount of aluminium composite material (ACM), the same cladding used on Grenfell Tower in London, where up to 80 people died in a fire in June.

Scottish Government officials are now helping Glasgow City Council with their audit of the housing after saying it had not been provided with a sufficient amount of detail about the findings.

Aitken hopes the necessary information will be found "by the end of next week" but it has also emerged the council previously rejected two offers of help from the Scottish Government.

In a letter to a Holyrood's local government and communities committee convener Bob Doris, Aitken said: "Glasgow City Council will inform residents in affected properties, by letter, when the additional information is gathered."

The discovery was only made public after a council official, Raymond Barlow, was pressed on the matter by Doris at a committee meeting after he said he detected "nervousness" in the answers given by the local government employee.

Local government and housing minister Kevin Stewart slammed the council in a letter sent to Doris following the committee hearing.

Stewart accused the authority of providing the devolved government with "unclear" information about the ACM findings which were so poor it could not give the necessary "public reassurance" over the matter.

As part of the letter to the committee, Stewart released a stash of communications between devolved and Glasgow City Council officials on the matter over the last few months.

Some of the 57 properties have ACM in panels between windows while some appear to have it on entire storeys, according to a table inside one of the emails sent by Mr Barlow to the government.
