There seem to be two aspects and press reporters mainly focusing on whether or not she should have noticed her husband's spending.
But also as SNP leader she apparently has a (joint) responsibility for SNP finances and whilst I'm no accountant I'd have thought that normal accounting practices would have spotted that degree of embezzlement. eg who (or how many people) would have had to sign-off on the purchase of a motorhome?
It's all very murky, because the accounts were also getting signed off by a (Scottish obviously) accountancy firm.
But out of all of the SNP top brass in that period, Murrell, Salmond, Sturgeon, Beattie, Swinney, all have left and other than Salmond (who left so long ago as to alhave avoided association with the embezzlement) been reputationally damaged. Except Swinney.
I hope the calls for more transparency do not get ignored, because there was a lot of public money going into the SNP as well.
