§ Mr. Thurnham
To ask the Secretary of State for the Home Department what is his best estimate of the number of previously convicted child sex offenders who will not be required to register under the terms of the Sex Offenders Bill. 
§ Mr. Maclean
This is a highly complex matter. No precise estimate is available of the number requested. Officials are preparing a paper containing estimates of various categories of sex offender which I will send to the hon. Member. Copies of the paper will be placed in the Library.
