Dagenham, the problem is, like everything behind the "Yes" vote, nothing about taxation has been even discussed in such detail, let alone cast in stone.
Scotland may find itself in difficult financial conditions for a whole host of reasons and once the plug has been pulled, no-one knows what will happen.
If Scotland really thinks that the present position can be no worse than under the present arrangement, then I say let it find out.
But I don't want the rest of UK being put in the situation where it has to "do a Merkel" and bail them out of debt when / if Scotland finds it's all going down the pan.
