Northern Ireland is set to go to the polls once more on July 4 after Prime Minister Rishi Sunak announced that he has called a General Election.

This upcoming election will be the first fought on the new constituency boundaries which came into force earlier this year following a series of public consultations which began in 2021.

While Northern Ireland will maintain 18 constituencies, there have been changes to their geographical areas and South Belfast has been renamed South Belfast and Mid Down.

The new South Belfast and Mid Down constituency will have an electorate of 71,978 people - an increase on the 70,134 in the existing Belfast South constituency.

Meanwhile East Antrim, will take in swathes of neighbouring North Antrim and Foyle will be reduced in size, with parts of the current constituency moving into West Tyrone and East Londonderry.

The electorate for Foyle will fall from 74,431 to 69,890 under the recommendations. Elsewhere, there will be minor changes to the other constituencies.

The changes came about after The Parliamentary Constituencies Act 2020 required that most seats have between 69,724 and 77,062 voters.

Constituency boundaries last changed at the 2010 general election. Previous boundary reviews were held in 2013 and 2018, following the passage of the 2011 Parliamentary Voting System and Constituencies Act. If implemented, these reviews would have reduced the number of seats in parliament from 650 to 600.

However, neither review was implemented. The 2013 reforms were blocked by MPs and the 2018 boundary review was scrapped in 2020 after the government argued that Brexit would increase MPs’ workloads.
