Hadn't realised that Midlothian, and presumably East Lothian, don't move to tier 2 until Tuesday. All the councils that moved to tier 4 did so on Friday at 6pm did they not?
So am I right in thinking if you move down a tier it happens the following Friday, but if you go up a tier you have to wait a week?
Looking at those numbers, yes, every chance their 'promotion' will be cancelled.
