Perhaps the hon. Lady might do the sums for herself. I said to her that through the screening service we expected to make contact with about 13 million women in this country. We expect to call them in approximately equal tranches over a five-year period. I also said that anyone who has never been called for screening—I have made this point on many occasions—can come in at any time. We tell people that if they are symptomless, there is no need to worry. I am content with that. It would not be possible to call in 13 million in the next six weeks and screen them all at once.
