Scotland Bill

My hon. Friend raises a pertinent point, because although we hear demands for powers made by certain parties, no purpose is ever given for the devolution of those powers. It is a staggering omission that we know absolutely nothing about the future of stamp duty land tax, given that it is due to be devolved to Holyrood in just a few short years. We have heard about the lack of evidence provided for the devolution of other taxes, with the Institute for Fiscal Studies setting out convincing evidence in its ““Green Budget”” a few months ago that devolving corporation tax would involve a race to the bottom and be a very risky endeavour indeed.
