Robin McAlpine is the director of the Scottish left think-tank Common Weal. As he revealed in a podcast this weekend (listen to the last couple of minutes), I have written a White Paper on taxation in the series that they are producing on preparation for an independent Scotland.
The White Paper is, in his opinion, radical. It also, and perhaps inevitably, promotes the idea of Scotland having its own currency, with that currency and the tax system being inextricably linked in the process of managing the Scottish economy.
There will be more on this soon. The launch will, I gather, be in the next couple of weeks. I will be in Scotland on 14 August, but not for this. I am back on 5th to 8th October for a series of events, some very definitely on this issue. There will be more details as soon as I know them.
