Mr. John McKeon:

That is exactly why we do the control surveys - to inform our control approach. As I explained earlier, what we have done up to now is write to a large number of people in receipt of pensions every year who had declared means. We knew they had means and we say, "Listen, if things have changed, will you please tell us?" We are now going to issue 10,000 letters a year to people who have new means and where it has been a number of years since they last claimed, reminding them that if their means have changed, they need to tell us.
