I wholeheartedly agree with the right hon. Lady. We have to make it absolutely clear that although we do not know the exact numbers, we have never based our case for concern on the overall numbers; it is enough if even one woman has been kidnapped, brought across borders to this country and bought and sold like a modern-day slave. When I was Solicitor-General, I came across one case in which two gangs brought a girl to a supermarket car park and bartered over her; she was sold from one gang to the other. If there is even one case such as that-and there are many more-that is enough for us to take tough action.

I take this opportunity to deplore the reporting in The Guardian; it sought to imply that because we did not know the specific numbers, or because some estimate had been wrong, somehow we were on the wrong track. Those involved should be ashamed of themselves.
