I find myself in a dilemma. Having agreed to take part in one of Alex Salmond’s stage shows during his live Scottish tour to talk about women in journalism, I now wonder - could he contaminate my credibility? It’s a strange state of affairs, I know. After all, Salmond is, in my opinion, one of the great political giants of our times. You don’t need to like him to recognise that he has 30 years’ experience as an astute parliamentarian both at Westminster and Holyrood.
