These Regulations amend the Special Constables Regulations 1965 by inserting provisions about the biometric vetting of candidates for appointment as special constables, about the testing of special constables, and candidates for substance misuse, and about the notification and approval of business interests held by special constables, candidates and their relatives. The inserted provisions are effectively identical to those applicable to regular police officers by virtue of the Police Regulations 2003. The relevant provisions of the Police Regulations 2003 are regulations 7 to 10, 19 and 19A.
