The Police Service of Northern Ireland (PSNI; Irish: Seirbhís Póilíneachta Thuaisceart Éireann; Ulster Scots: Polis Service o Norlin Airlan), is the police service responsible for law enforcement and the prevention of crime within Northern Ireland.
It is the successor to the Royal Ulster Constabulary (RUC) after it was reformed and renamed in 2001 on the recommendation of the Patten Report.
The St Andrews Agreement (Irish: Comhaontú Chill Rímhinn; Ulster Scots: St Andra's 'Greement, St Andrew's Greeance or St Andrae's Greeance) is an agreement between the British and Irish governments and Northern Ireland's political parties in relation to the devolution of power in the region. The agreement resulted from multi-party talks held in St Andrews in Fife, Scotland, from 11 to 13 October 2006, between the two governments and all the major parties in Northern Ireland, including the two largest, the Democratic Unionist Party (DUP) and Sinn Féin. It resulted in the restoration of the Northern Ireland Assembly, the formation (on 8 May 2007) of a new Northern Ireland Executive and a decision by Sinn Féin to support the Police Service of Northern Ireland, courts and rule of law.
Dissident republicans (Irish: poblachtach easaontach) are Irish republicans who do not support the Northern Ireland peace process. The peace agreements followed a 30-year conflict known as the Troubles, in which over 3,500 people were killed and 47,500 injured, and in which republican paramilitary groups such as the Provisional Irish Republican Army waged a campaign to bring about a united Ireland. Negotiations in the 1990s led to a Provisional IRA ceasefire in 1994 and to the Good Friday Agreement of 1998. Mainstream republicans, represented by Sinn Féin, supported the Agreement as a means of achieving Irish unity peacefully. Dissidents saw this as an abandonment of the goal of an independent Irish republic and acceptance of partition. They hold that the Northern Ireland Assembly and Police Service of Northern Ireland (PSNI) are illegitimate and see the PSNI as a British paramilitary police force.
Some dissident republican political groups, such as Republican Sinn Féin and the 32 County Sovereignty Movement, support political violence against the British security forces and oppose the Provisional IRA's 1994 ceasefire; other groups, such as the Irish Republican Socialist Party, wish to achieve their goals only through peaceful means.
The Northern Ireland Policing Board (Irish: Bord Póilíneachta Thuaisceart Éireann, Ulster-Scots: Norlin Airlan Polisin Boord) is the police authority for Northern Ireland, charged with supervising the activities of the Police Service of Northern Ireland (PSNI). It is a non-departmental public body composed of members of the Northern Ireland Assembly and independent citizens who are appointed by the Minister of Justice using the Nolan principles for public appointments.
A police authority in the United Kingdom was a public authority that is responsible for overseeing the operations of a police force. The nature and composition of police authorities has varied over time, and there are now just four dedicated "police authorities" in the United Kingdom, although the term can refer to various similar successor bodies.
Until 2012/13, individual police authorities were maintained for each of the 43 territorial police forces in England and Wales, and for the 8 territorial police forces in Scotland. Police authorities in England and Wales were abolished in November 2012, and replaced with directly elected police and crime commissioners, and those in Scotland were merged in April 2013 to form the Scottish Police Authority as part of the creation of Police Scotland, the single police force for Scotland. The Police Service of Northern Ireland is overseen by the Northern Ireland Policing Board, and two of the three UK-wide special police forces continue to be overseen by individual police authorities. The oversight of the two police forces serving London continues to be implemented via unique arrangements.
Law enforcement in the United Kingdom is organised separately in each of the legal systems of the United Kingdom: England and Wales, Scotland, and Northern Ireland. Most law enforcement duties are carried out by police constables of a territorial police force.
As of 2021, there were 39 territorial police forces in England, 4 in Wales, one in Scotland, and one in Northern Ireland. Each is responsible for most law enforcement and crime reduction in its police area. The territorial police forces of England and Wales are overseen by the Home Office and by a police and crime commissioner or other police authority, although they are operationally independent from government. The British Transport Police (BTP), the Ministry of Defence Police (MDP), and the Civil Nuclear Constabulary (CNC) provide specialist policing services in England, Scotland and Wales. The National Crime Agency (NCA) is primarily tasked with tackling organised crime and has been compared to the Federal Bureau of Investigation (FBI) in the United States.
Dyfed-Powys Police (Welsh: Heddlu Dyfed-Powys; DPP) is the territorial police force in Wales policing Carmarthenshire, Ceredigion and Pembrokeshire (which make up the former administrative area of Dyfed) and the unitary authority of Powys (covering Brecknockshire, Radnorshire and Montgomeryshire).
The Dyfed-Powys region covers an area of 3,360 square miles (8,700 km), with over 350 miles (560 km) of coastline. In terms of geographic areas of responsibility, Dyfed-Powys is the largest police force in England and Wales and the third largest in the United Kingdom after Police Scotland and the Police Service of Northern Ireland. It includes many remote rural communities and a number of old industrial areas that are currently undergoing significant change and redevelopment. The population is under 500,000, although it is boosted each year with many tourist visitors.
