There was a sense that Nicholas Sturgeon's hold on the SNP was loosening. It was clear that her control of the party was slipping and that her time was coming up. The introduction of this policy coincided with a big round in Scotland over whether a double rapist who was transgender should be placed in a woman's prison. And so that really did cement the idea that she wasn't quite on top of her party as she historically has been. We don't know, in part as a product of the dominance of Sturgeon in running the S&P and Scottish government that there isn't an obvious successor in place.
