Michael Matheson’s resignation letter is a paean of praise to himself, with claims about having introduced “world-leading” domestic abuse legislation and Scotwind leasing, although the latter brought in far less revenue than comparable schemes in the rest of the UK. What really sticks in my craw is the complete absence of any vestige of contrition, let alone apology. And to cap it all, he has the brass neck to sign off with the Salmondesque “Yours for Scotland”. How dare he? As far as I am concerned, he has disgraced Scotland and, apart from his obvious sins, has wasted people’s time, and therefore our money, on prevarications that have been investigated. It seems to me that Mr Matheson speaks only for himself, and without much self-awareness. Jill Stephenson, Edinburgh.
