The STV system up here means that counts can be a little slow (some counts won't declare till late afternoon/early evening) and transfer votes can lead to unpredictable outcomes via tactical ranking of preferences. This isn't helped by confusion about the voting system in the polling booth. Quite a few people marked their ballots with a cross rather than ranking them. As long as they marked just one cross, that should be taken as their first and only preference, but these votes are being routinely challenged in many counts. After this election's results there'll be a lot of horse trading and coalitions or looser alliances in various councils.
Significant developments so far (change since last election):
Aberdeen
SNP 19 (+4)
Tory 11 (+8)
Labour 9 (-8)
LibDem 4 (-1)#
Independents 2 (-1)
No overall control. SNP could run a minority administration, or Labour could call the shots by allying with either the SNP or the Tories. The last administration was a Labour/Tory/Independent coalition. Controversial and recently scandal-ridden council leader Labour's Willie Young lost his seat.
Glasgow
Labour has lost its historic majority. Not clear yet whether the SNP will have a clear majority.
This is a snapshot of the current state of play in Scotland as a whole:
