As an economics graduate I know the question in a room full of economists how may theories on any economic issues are in the room? The answer for those less au fait with a gathering of economist is n+1 where n is the number of economists present.
However, over the last week I've come to the conclusion that like those children's day a week underpants sets Wendy Alexander must have been given a week long policy a day set over independence.
From bring it on a personal statement, it gained the backing of the MSPs, but the PM turned his back on it saying it was a matter for the Scottish Leader, who then said she'd bring her own policy paper for a quicker referendum, to losing the backing of the party's Scottish National Exec at the weekend. We now have her not going to stand in the way of the SNPs own policy proposal on the issue.
Or dear, one Sunday Wendy Alexander finds a rocky promontory to stand on, but after a week and a day of gales, realising it was a slippery rock and that she did not really have a hold and support of those standing behind her, she's run unto the beach, only to get stuck in the sand.
Maybe she'll considering burying her sand in it for a while as the Nats will just attack her, her own party just stalk her, the Tories and Lib Dems at Holyrood mock her, and those pro-referendum pro-union supporters are still scratching their heads trying to ascertain whether she's done any good or damage to the whole issue with her whole random policy making this week, based on which set of undies she's been wearing.
