However, this was Friday's run of the model. The simulations have now reached a tipping point where the bulk of SNP target seats moved out of a variance range where they could be defended.
The result is that in the majority of simulations, the SNP win a landslide in Scotland. The model now has a staggering 70% probability that the SNP will hold the balance of power in a hung parliament, and based on statements made by the party leaders that can be interpreted as a Labour minority government. There is only a total 4% of simulations showing any party having a majority, with Labour reduced to the same level as the Conservatives. However, they still retain a moderate edge over the Conservatives on being able to form coalition with the LibDems, at 13% to 5%. With the possibility of UKIP-Conservative coalition still being all but ruled out as they fail to establish general election wins in any simulation run at all.
I say this is only "moderately" important a change, because the model had already predicted that the SNP would hold the balance of power. This "merely" moves it into that much higher a probability with a likely landslide north of the border.
