The Home Office (HO), also known as the Home Department, is a ministerial department of the Government of the United Kingdom. It is 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, Border Force, visas and immigration, and the Security Service (MI5). It is also in charge of government policy on security-related issues such as drugs, counterterrorism, and immigration. 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.
