The Jeremy Kyle Show's bosses have been criticised by MPs for putting guests through lie detector tests without knowing how accurate those tests were.
Damian Collins MP, chair of the House of Commons culture select committee, said the producers' lack of expert knowledge was "astonishing".
The committee opened an inquiry after Kyle's show was axed in May, following the death of participant Steve Dymond.
Mr Dymond, 63, died around a week after reportedly failing a lie detector test.
