My hon. Friend brings me to an important point, which is that, over the course of this Parliament, the Government have been determined to address stamp duty land tax avoidance. It was a problem in the tax system. One certainly heard both anecdotally, and in the concerns of HMRC, of transactions being made to envelope properties and so on, which is why in 2012 we announced the introduction of the annual tax on envelope dwellings. It is why, over the course of this Parliament, we have taken a number of actions to deal with that avoidance. Had we not done so, it would have been difficult to make the reforms that we have in front of us today in an affordable way, as we would not effectively have been able to raise additional revenue from the top end of the housing market to counteract the reductions in revenue that will occur in the rest of the market.
Increasing rates would not have led to much, if anything, by way of additional revenue, because we would have found that it would have increased avoidance activity and we would not have got in the money that we would otherwise have done. As a consequence, the costs would have been unaffordable.
