David Blunkett has strongly hinted that he wants to introduce compulsory lie detector tests for the first time for convicted sex offenders released from prison.

A decision on the introduction of the tests is to be taken by the government this summer.

The home secretary has also announced that new American satellite tagging technology is to be tested in England and Wales later this year to track the whereabouts of serious offenders at all times.

He was speaking during a Labour Big Conversation event in Oxford.
