Northern Ireland Executive - Structure

Structure

In contrast with Westminster system cabinets, which generally need only be backed by a majority of legislators, ministerial positions in the Northern Ireland Executive are allocated to parties with significant representation in the Assembly. With the exception of justice, the number of ministries to which each party is entitled is determined by the D'Hondt system.

In effect, major parties cannot be excluded from participation in government and power-sharing is enforced by the system. The form of government is therefore known as mandatory coalition as opposed to voluntary coalition where parties negotiate an agreement to share power. The Democratic Unionist Party (DUP), the Ulster Unionist Party (UUP), the Alliance Party of Northern Ireland and some Social Democratic and Labour Party (SDLP) members favour a move towards voluntary coalition in the longer term but this is currently opposed by Sinn Féin.

The Executive can not function if either of the two largest parties refuse to take part, as these parties are allocated the First Minister and deputy First Minister positions. However, other parties are not required to enter the Executive even if they are entitled to do so; instead, they can choose to go into opposition if they wish. There were some calls for the SDLP and the UUP to enter opposition after the 2007 Assembly elections, but ultimately the two parties chose to take the seats in the Executive to which they were entitled.

In 2010, an exception to the D'Hondt system for allocating the number of ministerial portfolios was made under the Hillsborough Castle Agreement to allow the cross-community Alliance Party of Northern Ireland to hold the politically-contentious policing and justice brief when most of those powers were devolved to the Assembly. Devolution took place on 12 April 2010.

Under D'Hondt, the SDLP would have been entitled to the extra ministerial seat on the revised Executive created by the devolution of policing and justice. Accordingly both the UUP and SDLP protested that Alliance was not entitled, under the rules of the Good Friday Agreement, to fill the portfolio and refused to support this move. However, Alliance leader David Ford was elected Minister with the support of the Democratic Unionist Party and Sinn Féin.
