Question to the Ministry of Justice:

To ask Her Majesty’s Government how many persons imprisoned for sexual offences have been returned to prison after failing lie detector tests by polygraph; and how many were referred for polygraph tests in the last period for which statistics are available.

Polygraph tests for certain sexual offenders on licensed supervision in the community first became available in August 2014. As of October 2015, 681 sexual offenders had been made subject to polygraph testing as a license condition and had been referred for testing to the National Offender Management Service. As of the same date, 22 sexual offenders were recalled as a result of disclosures which they had made in connection with their polygraph test, whilst one was recalled for failing to attend a test which had been arranged.
