Overview
An interior minister (sometimes called a minister of internal affairs or minister of home affairs) is a cabinet official position that is responsible for internal affairs, such as public security, civil registration and identification, emergency management, supervision of regional and local governments, conduct of elections, public administration and immigration (including passport issuance) matters. This position is head of a department that is often called an interior ministry, a ministry of internal affairs or a ministry of home affairs. In some jurisdictions, there is no department called an "interior ministry", but the relevant responsibilities are allocated to other departments.
Remit and role
In some countries, the public security portfolio belongs to a separate ministry (under a title like "ministry of public order" or "ministry of security"), with the interior ministry being limited to control over local governments, public administration, elections and similar matters. Notable examples include Greece (Ministry of Citizen Protection) and Israel (Ministry of Public Security). In some jurisdictions, matters relating to the maintenance of law and order and the administration of justice are the responsibility of a separate justice ministry.
In countries with a federal constitution, interior ministers will often be found at both the federal and sub-national levels. Similarly, autonomous entities and dependent territories may also have interior ministers.
By country
In the United Kingdom, the position of Secretary of State for the Home Department, normally referred to as the "Home Secretary", was created in the British governmental reorganisation of 1782.
