Overview
The secretary of state for Northern Ireland, also referred to as the Northern Ireland secretary or SoSNI, is a secretary of state in the Government of the United Kingdom, with overall responsibility for the Northern Ireland Office. The incumbent is a member of the Cabinet of the United Kingdom.
The office holder works alongside the other Northern Ireland Office ministers. The corresponding shadow minister is the Shadow Secretary of State for Northern Ireland.
History
Historically, the principal ministers for Irish (and subsequently Northern Ireland) affairs in the UK Government and its predecessors were:
the Lord Lieutenant of Ireland (c.1171–1922);
the Chief Secretary for Ireland (1560–1922); and
the Home Secretary (1922–1972).
In August 1969, for example, Home Secretary James Callaghan approved the sending of British Army soldiers to Northern Ireland. Scotland and Wales were represented by the Secretary of State for Scotland and Secretary of State for Wales from 1885 and 1964 respectively, but Northern Ireland remained separate, owing to the devolved Government of Northern Ireland and Parliament of Northern Ireland.
