Cole-Hamilton: How can ministers guarantee concrete collapse is isolated incident?

Speaking in this afternoon's Scottish Parliament statement on Reinforced Autoclaved Aerated Concrete (RAAC), Scottish Liberal Democrat leader Alex Cole-Hamilton said:

"If ministers were really across this problem, don’t you think Parliament and the public would have been told sooner that at least 40 schools and an untold number of hospitals contain this potentially lethal concrete.

"Ministers were nowhere near even understanding this. No money was put aside.

"Instead, Liberal Democrats, not the government, were the first to lay bare the scale of the problem.

"Indeed, the trigger for schools closing in England was a concrete beam failing at a school in Dunblane. A beam that was rated as safe, but it failed. The Scottish Education Secretary said on Channel 4 News last night that “was an isolated incident”.

"Does the minister agree with her Cabinet colleague? How does she know this won’t happen again, especially as we don't know where this concrete is and how it has been used?"
