Glasgow City Council has apologised for alarm caused after it emerged private properties across the city are clad in aluminium similar to Grenfell in London.

Up to 57 private high-rises in the city could feature the same type of cladding used in the London tower block where 80 lives were lost in a fire.

Council leader Susan Aitken conceded the revelation, at a Holyrood committee meeting last week, was a surprise to her.

Speaking to STV, she said: "This problem came about because information that was incomplete emerged prematurely, for which I can only apologise to anyone who has been alarmed or distressed by that happening.

"That should never have happened but once it did we had to make sure the problem wasn't compounded by other incomplete information.

"My task over the past week has been ensuring we have the fullest possible amount of information and we are in a position to tell people what is going to happen and when it's going to happen."

Aitken said the information was never intended to come out at the committee meeting and apologised "unreservedly" for any alarm caused.

She said the full extent of the situation will be known by Friday, with any residents affected being informed by letter immediately afterwards.

The council believes the situation is not serious and does not affect many households.

"All of the evidence we have so far indicates we will be able to reassure residents that they are not at risk," she said.

"It is not our expectation that there is any immediate danger or concern for residents.

"Had any of the investigations identified that, there would have been immediate action taken."

Aitken has faced criticism from some MSPs over her handling of the affair.

The SNP's Bob Doris accused the council on Wednesday of causing "undue alarm" to residents.

Ms Aitken believes the council acted responsibly, however.

She said: "The instructions I gave inspectors were to not compound the initial mistake by releasing incomplete information that would have raised further alarm.

"I apologise to people who felt distressed or worried. It shouldn't have happened. But it would have been worse if we released inaccurate information."
