Defra recently circulated a new document detailing the Minimum operating standards fro UK approved Passport Issuing Organisations (PIO's).

Defra recognise that there is still some ongoing work to do, but feel that this document represents "a big step in the right direction for strengthening the horse passports regine" and will now work towards getting an audit programme set up to help ensure that these standards are being met.
