Who can vote?
You can register to vote in elections to the Northern Ireland Assembly if you are a British, Irish or Commonwealth citizen, or if you are a citizen of an EU Member State.
You must be 18 to vote in Northern Ireland, although you can register to vote once you are 17.
What happened during the 2017 legislative elections?
The 2017 Northern Ireland Assembly election was significant as it was the first election since MP seats were reduced from 108 to 90. The DUP, the largest party, suffered the brunt of this reduction and lost 10 seats.
Despite this, the DUP remained the largest party with 28.1% of the vote. Sinn Féin finished second by a very slim margin at 27.9%.
The renewable heat incitement scandal was a big talking point in 2017. The scandal, a failed renewable energy initiative that reportedly cost the public £500m, inflamed tensions between the DUP and the Sinn Fein.
Arlene Foster, former leader of the DUP, was at the heart of the scandal. She has since resigned.
What could happen in 2022?
All signs ahead of the vote pointed to a Sinn Féin victory, which would be a landmark event in Northern Ireland’s electoral history.
Co-operation between Unionist and Nationalist parties in Ireland has broken down in recent years and a victory for Sinn Féin could lead to a further escalation of animosity between the two camps.
Despite the obvious implications for the Union, Sinn Fein’s campaign has shifted attention to other issues, in particular the cost of living crisis which has affected the whole country.
Election results are expected to be announced throughout Friday.
