Memo to Jackanory Jim : be careful what you wish for

Labour have been busily feigning outrage for weeks that Alex Salmond wasn't taking part in two of the three Scottish side-debates, so you'd probably imagine they will now be pronouncing themselves thoroughly satisfied with his change of heart about tomorrow's final BBC debate. Er...no, actually. If the early reaction of a Labour activist on Twitter is anything to go by, it appears they're attempting a seamless switch back to the "what-does-he-want-to-take-part-for, he's-not-even-a-candidate-in-this-election" line.

Jeez. Sort it out, guys.

In spite of what I said about this a couple of weeks ago, I'm sure this is absolutely the right call by the SNP. The three rigged UK-wide debates have now been broadcast, and strategies for preventing a repeat of that outrage can be left for another day. For now, it's all about taking every last opportunity to maximise the SNP's vote in this election. Jim Murphy will be privately horrified that his slightly creepy Jackanory-style storytelling approach to debating is about to face the full Eck treatment for a second time.
