Residents of 19 tower blocks in Glasgow are being sent letters confirming their buildings contain cladding similar to that used on Grenfell Tower.

Glasgow City Council revealed combustible cladding was found on 57 private high rise buildings but further investigation has reduced that total to 19.

People living in flats in these buildings are being given hand-delivered letters informing them of the situation.

The local authority, which is the largest in Scotland, confirmed letters were delivered on Friday but refused to say which blocks were affected.

MSPs on the Scottish Parliament's local government committee heard last week from a senior council official that a search in the aftermath of the Grenfell tragedy in London found combustible cladding on some private flats.

Despite the discovery the council did not inform the owners of the buildings or those living in them.

Raymond Barlow, the assistant head of planning and building standards at Glasgow City Council, said at the time the authority had been waiting to hear from the Scottish Government on the issue.

Glasgow City Council leader Susan Aitken has since apologised for the alarm caused to residents by the revelation.

Speaking earlier this week she said: "It is not our expectation at this point that there is any immediate danger or concern for residents."

Police believe at least 80 people died when fire engulfed Grenfell Tower in North Kensington, west London, in the early hours of June 14.

In the wake of the tragedy, the Scottish Government ordered councils to carry out checks to see if ACM (aluminium composite material) had been used on flats in their area.

Glasgow was the only authority to find this on properties but ministers criticised the council for the "lack of detail" in the information that was given to the ministerial working group on building and fire safety.

Bill Dodds, the head of building standards at the Scottish Government, said it was seeking "clarity" over the extent to which the cladding had been used.

Mr Dodds said: "In Grenfell, the entire building was overclad with ACM (aluminium composite material), it was a complete enclosure of ACM material so what we're trying to do is establish whether we have a Grenfell type arrangement where the building is completely overclad in ACM product or if it is in isolated areas, that's the clarity we're asking."

Staff from the Scottish Government were sent into the council this week to help them uncover the necessary information.
