Well it wouldn't be the first time would it? However they might look back on the aftermath of the 1970's as a bad precedent. ......
Just to enhance, by that I mean every time Labour has got in with less of a majority of votes than the number of Scottish seats, they have been governing with a Scots influence. OK so it's more visible with SNP, but still pretty much the same... In fact Labour insiders are more likely to force Scottish issues than SNP in coalition.
The SNP may well coalition with Labour to govern, but that presumes that Labour is the biggest single party. If they are not and it's not looking good for them, then the Tories will never give them the chance, as they did in the last election...
Look forward to more coalitions as time goes on. More strong parties == less single governments and more coalitions. Perhaps, then, our government will come to understand the EU governments much better???
