DPF meaning in Governmental ?

The Defence Police Federation (DPF) is the representative body of Ministry of Defence Police (MDP) officers, up to and including the rank of Chief Superintendent. There are around 2,000 members as of 2014. Membership is restricted by law to serving officers. MDP officers have their own federation because they are also part of the Civil Service and are accountable to the Secretary of State for Defence, and not the Home Secretary. Moreover, MDP officers have different terms and conditions of service to civilian police officers. Officers' pay is directly linked to national settlements made by the Home Office and the Police Federation of England and Wales. The DPF also administer the Defence Police Retired Officers Association. With an 'all armed' membership, the DPF maintains close ties with the Police Firearms Officers Association (PFOA); as of 1 October 2014 all DPF members, have automatic membership of the PFOA.
