Electoral system

s were elected in 18 Single Member constituencies by first-past-the-post.

Background

The election was called on 29 October 2019 under the Early Parliamentary General Election Act 2019. At the 2017 election, the nationalist Social Democratic and Labour Party and the Ulster Unionist Party lost all of their seats. The DUP won 10 seats, Sinn Féin won 7 seats, and Independent Unionist Sylvia Hermon was also elected. The election ended in a hung parliament, and the Democratic Unionist Party signed a confidence and supply agreement with the Conservative Party.
In 2018, Sinn Féin MP for West Tyrone, Barry McElduff, resigned after a social media post he made caused controversy regarding perceived sectarianism on the Kingsmill massacre. The party won a by-election later, but with a plurality instead of a majority.
In the 2019 European Parliament election, Sinn Féin, the DUP, and the Alliance Party each won a seat.

Participating parties

102 candidates stood in the general election. The Alliance Party was the only party standing in all 18 seats. The DUP stood in 17 seats, the UUP in 16, and both Sinn Féin and the SDLP in 15 seats. Aontú stood in 7 seats, the Northern Ireland Conservatives in 4, the Green Party of Northern Ireland in 3, and People Before Profit and the UK Independence Party in 2. Traditional Unionist Voice did not stand in this election. There were also three independent candidates. Sylvia Hermon did not contest this election.
Sinn Féin operates on an all-Ireland basis. Their MPs in Westminster practice abstentionism, meaning they do not take their seats in the House of Commons. Aontú, who like Sinn Féin are an abstentionist all-Ireland party, was formed in January 2019.
