The spokesman added: “If an individual is successful in their application for a post requiring disclosure, they are required to authorise the council to apply for disclosure of information from the Disclosure and Barring Service (DBS).
“The DBS is a central government agency which provides information on criminal records, and people banned from regulated activity with vulnerable groups, including children.
“As part of the agreement with the DBS, the council conforms to the codes of practice it publishes regarding disclosure. “
“The council does not hold a list of convictions that automatically bar applicants from job roles however the DBS carries out a barred list check on eligible positions.”
