Humza Yousaf has revealed a dark truth about the SNP

American journalist Michael Kinsley once observed that in Washington DC a ‘gaffe’ should be understood as a moment in which a politician or public official inadvertently blurts out a truth it would have been better, and certainly wiser, to leave unsaid. By that standard Humza Yousaf, currently serving as health secretary in the Scottish government, is a mighty friend to journalists.

Pondering the meaning and significance of what has become known as the Alex Salmond affair, Yousaf told the comedian Matt Forde that the conflict between Salmond and Nicola Sturgeon was ‘really upsetting because it could have done our cause a hell of a lot of damage – it still might do our cause a hell of a lot of damage’. Sometimes it is better not to say the quiet bit out loud. But nevertheless, Yousaf’s remarks were a form of public service. For they revealed a deep, dark, truth about the SNP.
