Keegan asked to stress urgency to Scotlandpublished at 17:51 British Summer Time 4 September 2023
Christine Jardine from the Liberal Democrats is up next.
She asks Keegan to impress on the prime minister that this is a problem of "national scale" and will affect other public buildings.
Jardine also asks Keegan to press the Scottish government on the urgency of the situation.
The education secretary responds by saying the government could go through the responsible bodies, and says that is what they were doing until 2019.
However, she says the government didn't think it was being quick enough, which is why the government started the direct questionnaire and surveying programme.
Keegan adds "sometimes it's right to take direct approach".
