I will make two points in response to the hon. Lady: first, she mentioned profit shifting, and we have been in the vanguard of the OECD base erosion and profit shifting project—right at the forefront, driving it forward and, indeed, implementing it in many areas earlier than other countries decided to. Secondly, I believe that our overall record is exemplary and world-class; but of course there is always more to be done. It is absolutely right and proper that those who owe tax pay it, and where HMRC or the Treasury come across schemes that use various artificial devices to avoid and evade tax we will clamp down on those measures with vigour. We have demonstrated our success in doing so in the past, and will continue to do so in the future. The clause is yet another step in pursuing that endeavour.
