Ms.Sturgeon has truly dug herself into a hole of her own making. This "call my bluff" posturing could mean that in order not to look foolish she will feel obliged to call a second independence referendum whilst in the knowledge that the majority of the Scottish people (according to the opinion polls) don't want independence! If the people say "no" a second time then she will have lost any credibility she has left and will have to stand down as leader of the SNP.
