He's blown it now. The giddy heights of "professor" will be as good as it gets for Lindsay Paterson. Royal Commission chairmanships and the knighthood have definitely gone.
The Edinburgh University educationist described Sam Galbraith as "bullying and arrogant" in a newspaper letter last week. And in a weekend article, Paterson suggested that the great exams crisis would be what the unfortunate Galbraith will be remembered for as he presided over the "disastrous complacency" of the leadership class.
What on earth has Dr Sam done to Professor Lindsay to provoke such fury? It is presumably nothing personal. Can it really be about the SQA? More likely perhaps, a touch of revenge for the minister's recent attacks on researchers?
And Paterson has a reputation for going over the top. While other members of the Broadcasting Council for Scotland continued to fight the good fight in favour of the Scottish Six TV news agenda, his fury with London BBC high heid-yins led to a walk out amid invective.
