2016 Northern Ireland Assembly election
# 2016 Northern Ireland Assembly election

The 2016 Northern Ireland Assembly election was held on Thursday, 5 May 2016. It was the fifth election to take place since the devolved assembly was established in 1998. 1,281,595 individuals were registered to vote in the election (representing an increase of 5.9% compared to the previous Assembly election). Turnout in the 2016 Assembly election was 703,744 (54.9%), a decline of less than one percentage point from the previous Assembly Election in 2011, but down 15 percentage points from the first election to the Assembly held in 1998.

As in the 2007 and 2011 elections, the Democratic Unionist Party and Sinn Féin won the most seats, with the DUP winning 38 and Sinn Féin winning 28 of the available 108 seats. The Ulster Unionist Party won 16 seats, the Social Democratic and Labour Party 12 and the Alliance 8, while two seats were won by the Green Party and People Before Profit. The Traditional Unionist Voice and an independent candidate each won one seat.

## Change of date

Under the Northern Ireland Act 1998, elections to the Assembly were originally for a four-year term; thus there would have been an election due in May 2015, four years after the 2011 election. Following the introduction of the UK Fixed Term Parliaments Act, this date would have clashed with the 2015 UK general election. The Scottish Parliament and Welsh Assembly elections were postponed for a year to 2016 to avoid this clash.

In May 2013, Theresa Villiers, Secretary of State for Northern Ireland, announced the next Assembly election would be postponed to May 2016, and would be held at fixed intervals of five years thereafter. Section 7 of the Northern Ireland (Miscellaneous Provisions) Act 2014 specifies that elections will be held on the first Thursday in May on the fifth (rather than fourth, as previously) calendar year following that in which its predecessor was elected.

## End of dual mandate

The Northern Ireland (Miscellaneous Provisions) Act 2014 also ends the practice of dual mandate, prohibiting someone being elected to the assembly who is also a member of the House of Commons or Dáil Éireann. At the time the Act was passed, there were three such dual-members: the DUP's Sammy Wilson (MP for East Antrim and MLA for East Antrim) and Gregory Campbell (MP for East Londonderry and MLA for East Londonderry) and the SDLP's Alasdair McDonnell (MP for Belfast South and MLA for Belfast South). Wilson and McDonnell resigned from the Assembly after being re-elected to the House of Commons in the 2015 election. Campbell, who was also re-elected as an MP, is retiring from the Assembly at this election.

## Earlier dissolution

There are several circumstances in which the Assembly could be dissolved before the date scheduled by virtue of section 31(1) of the Northern Ireland Act 1998.

### Dissolution motion

Under section 32 of the 1998 Act, the Assembly can be dissolved if a resolution to such an effect is passed by the Assembly, with support of 72 or more members.

### Failure to elect the First or deputy First Ministers

The Act provides that if the Assembly fails to elect either the First Minister or deputy First Minister within six weeks, an election is called. Since the enactment of the Northern Ireland (St Andrews Agreement) Act 2006, the First Minister has been nominated by the largest party of the largest community designation, and the deputy First Minister has been nominated by the largest party in the second largest community designation ("Nationalist", "Unionist" or "Other").

### New Executive Departments

It was proposed that after the May 2016 Election there be a reduction in the number of ministries and departments. The amendments were:

* The Office of the First Minister and deputy First Minister is renamed the Executive Office
* The Department of Agriculture and Rural Development is renamed the Department of Agriculture, Environment and Rural Affairs
* The Department of Enterprise, Trade and Investment is renamed the Department for the Economy
* The Department of Finance and Personnel is renamed the Department of Finance
* The Department of Health, Social Services and Public Safety is renamed the Department of Health
* The Department for Regional Development is renamed the Department for Infrastructure
* The Department for Social Development is renamed the Department for Communities
* The Department of Justice remains unchanged Department of Justice (Northern Ireland)
* The Department of Culture, Arts and Leisure is dissolved
* The Department of the Environment is dissolved
* The Department for Employment and Learning is dissolved

° The Department of Education remains the same.
