Are Scotland keeping their masks?
Seems so, for now anyway. The one-metre rule goes from next Monday but we're still being expected to wear masks in hospitality and public transport settings, and of course healthcare stuff. And we'll still be 'encouraged' to check in with phones/QR codes in pubs, restaurants etc. They're also still saying people should work from home 'where possible' although that's guidance rather than law I believe.
My gut says Sturgeon is anticipating a resurgence in the autumn/winter this year, and rather than do the hokey-cokey of mask rules that England will likely end up doing, thinks it'll probably play better if we keep them for the next few months, with the intention of getting properly rid next spring. It'll make her look more consistent and considered, which is no bad thing for her personal political brand.
With the devolved nations especially, up to now the leaders have had little to lose (politically) by appearing to be more cautious than Johnson, which isn't difficult. A lot of this is, I would wager, a positioning exercise.
That said, as the public mood shifts and it is shifting, slowly I think even the hawks like Sturgeon and Drakeford will find it harder to continue justifying the harsher measures, as there will be less and less political capital in it as time goes on. (Although if Sturgeon goes into government with the Greens here I think we'll start seeing some 'action' around climate along somewhat similar lines.)
