SIR Alex Ferguson's former primary school is set to be demolished after a major blaze ripped through the building.

Forty firefighters spent almost 12 hours battling a blaze at the derelict school in Broomloan Road, Govan, Glasgow. Staff at a Subway station raised the alarm after flames were spotted.

The fire broke out at Broomloan Nursery School at around 11pm on Tuesday and the building was "well alight" when firefighters arrived.

It is understood that the blaze is being treated as suspicious and the building will now be demolished over safety concerns.

Former Manchester United boss, Sir Alex, attended the school from 1946 until 1954.

Experts from building control were ­assessing the damage yesterday as crews continued to dampen down any remaining pockets of fire. Crews were forced to battle the blaze from the street after asbestos was found in the building.

An investigation, ­involving police and fire chiefs, is also under way to find the cause of the blaze.

Police closed several roads around the area because of the amount of smoke that filled the air.

There were no rep­orts of any injuries.

A spokeswoman for the Scottish Fire and Rescue Service said: "We were called at 10.57pm. Five appliances were sent to the incident."
