Ms Sturgeon said people would be appalled by Mr Miliband's refusal to consider a deal with her party.
"He sounded as if he was saying that he would rather see David Cameron and the Conservatives back in government than actually work with the SNP," she said.
"Now, if he means that then I don't think people in Scotland will ever forgive Labour for allowing the Conservatives back into office.
Should it happen, the people of Scotland would have nobody to blame but themselves. If they vote SNP in the belief that it is a "safe" protest vote, even though Ed Miliband has very explicitly ruled out any sort of deal with the SNP, and they end up with a minority tory government instead, then how is that Labour's fault? Perhaps next time they won't feel so confident protesting and will vote Labour instead. If it wasn't for non-nationalist socialists voting SNP in Scotland, we'd be looking at a Labour majority on May 8th.
It is simply not in Labour's long-term best interest to do a deal with SNP, regardless of how badly the SNP would like the situation to be otherwise.
But this does make the nature of the next government even harder to predict. I think we're looking at an unstable minority government, but at this point it is impossible to make a decent guess as to who will be running it and which parties will be involved. Fascinating stuff.
Miliband's comments torpedo this SNP tactic. After all, it wasn't Labour who let the tories in last time - it was the Liberal Democrats. So the above poster actually only makes sense in Scottish seats held by the LDs. In labour held seats, voting SNP might end up letting the tories in rather than locking them out.
Ed Miliband is not stupid.
