Scotland Bill

Perhaps I may ask my noble friend to consider the politics of this, as opposed to what the rule book says. I suggest that we look at the difficulty that the Government have at the moment in deciding whether to legislate on a referendum. That is clearly a matter for Westminster and not for the Scottish Parliament but the Government are doing cartwheels trying to find a way to use Section 30 because they do not want to be seen to be dictating to Scotland. If the Scottish Parliament, with this power, decides to create completely new taxes—perhaps putting up the top rate of tax to 60 per cent or removing the exemption for unearned income or whatever—does my noble friend really think that it will be practical politics for this House or even the other place to say that that is not going to happen because under criterion 4C it will influence macroeconomic policy? That is not real politics. A genie is being let out of the bottle here and we should not deceive ourselves about how radical this is as a proposal. I hope that my noble friend will address this for what it is and not for how it is presented.
