SNP should call Labour's bluff on referendum

Since the current Wendy Alexander brouhaha began I have argued that the SNP government, in its own interests, should call Ms Alexander's bluff by responding positively to her "bring it on" scenario for holding a referendum. I assume that the SNP goal remains an independent Scotland and not establishing a competent regime at Holyrood for our delectation and the approval of the chattering classes. For Ms Alexander has committed the biggest gaffe in Scottish public life for a generation, perhaps longer.
