I will give way in a moment, if the hon. Gentleman keeps calm.
Finally, as I have said, the issue of specific powers and what we might do with them is not all about tax: it is about other decision making, such as the minimum wage. We support a rise in the minimum wage to £8.70 by the end of this Parliament: that is the right thing to do. We do not currently have the power in Scotland to do that. Although we will table amendments to transfer that specific power, the last two examples demonstrate why we need full fiscal autonomy—to deliver a comprehensive, joined-up approach, which would allow us to increase the minimum wage to help those in employment who earn the least, while increasing the employment allowance to help support businesses to pay it.
