Apologies for the source, can't find anyone else tweeting it, but I've said before that Swinney and Forbes might row back from the higher taxes in Scotland. I've no idea what business are saying, but people don't generally like paying more tax themselves, and if they do, then it's not usually very much more. LIke a fiver a week out of a £60k salary.
The SNP have been seriously overcooking what the extra tax pays for too, when most of the extra over England it is down to UK wide transfers. So if this gets found out, they could fall further. I haven't seen any polling, but would be surprised if it wasn't a factor in Yes voters supporting Labour in the election.
My own feeling, as I always say when talking about Corbyn, is that to raise a lot more tax, you have to start very far down the income scale. The SNP haven't started that far down. but further down than most are prepared to contemplate. So though I don't like them, I'd be sorry to see this experiment end, if it does.
