The Home Office (HO), also known (especially in official papers and when referred to in Parliament) as the Home Department, is a ministerial department of the British Government, responsible for immigration, security, and law and order. As such, it is responsible for policing in England and Wales, fire and rescue services in England, visas and immigration, and the Security Service (MI5). It is also in charge of government policy on security-related issues such as drugs, counter-terrorism, and ID cards. It was formerly responsible for His Majesty's Prison Service and the National Probation Service, but these have been transferred to the Ministry of Justice.
The Cabinet minister responsible for the department is the Home Secretary, a post considered one of the Great Offices of State; it has been held since October 2022 by Rt Hon Suella Braverman MP. The Home Office is managed from day to day by a civil servant, the Permanent Under-Secretary of State of the Home Office.
The expenditure, administration, and policy of the Home Office are scrutinised by the Home Affairs Select Committee.
The Home Office is headed by the Home Secretary, a Cabinet minister supported by the department's senior civil servant, the permanent secretary.
