Under the Local Government Act 1888, an elected county council was set up to take over the functions of the Pembrokeshire Quarter Sessions. This and the administrative county of Pembrokeshire were abolished under the Local Government Act 1972, with Pembrokeshire forming two districts of the new county of Dyfed: South Pembrokeshire and Preseli – the split being made at the request of local authorities in the area. In 1996, under the Local Government (Wales) Act 1994, the county of Dyfed was broken up into its constituent parts, and Pembrokeshire has been a unitary authority since then. In 2017 Pembrokeshire County Council had 60 members and no political party in overall control; there were 34 independent councillors. In 2009, the question of county names and Royal Mail postal addresses was raised in the Westminster parliament; it was argued that Royal Mail's continued use of the county address Dyfed was causing concern and confusion in the Pembrokeshire business community. In 2018, Pembrokeshire County Council increased council tax by 12.5 per cent, the largest increase since 2004, but the county's council tax remains the lowest in Wales.
