Humza Yousaf’s victory in the SNP leadership election brings to mind the old joke about how you know the mafia is at a cockfight – the duck wins. Yousaf was, by a country mile, the weakest of the three candidates. Has he a trade or a profession? No. Has he significant experience from any job outside politics? No. Perhaps, he did a difficult degree at university -medicine, engineering, law? No, of course not. He read politics. Hu mza Yousaf brings nothing in the way of useful experience, education or insight to the world of politics. It is no surprise that as a consequence he has been reliably a failure in every ministerial post he has held. The only question is how long he will be allowed to fail as first minister? Otto Inglis, Crossgates.
