It is important to focus on the number of HMRC staff working on tax evasion and tax avoidance. Let me give two statistics: between 2005 and 2010 that number fell by 9,000, but between 2010 and 2015 it will increase by 2,500.
That is a very good question, but I am afraid I cannot give an answer to it. What I can say is that we have today published draft legislation for a general anti-abuse rule and it will come into force next year.
