Professor Jason Leitch has admitted it might have been a mistake to close schools during the Covid pandemic.
Scotland’s national clinical director said different decisions might have been made if the full impact of lockdown had been known.
Professor Leitch, who fronted the Covid campaign, added that he was drafted in for Scottish Government TV briefings over fears that only half the nation liked First Minister Nicola Sturgeon.
His comments appear to undermine the hardline tactics adopted by the Scottish and UK governments, which caused huge disruption to education, the NHS, businesses and society for two years.
