It was held on the same day as three other by-elections in Cork North-Central, Dublin Fingal and Dublin Mid-West.[1] The Electoral (Amendment) Act 2011 stipulates that a by-election in Ireland must be held within six months of a vacancy occurring.[2] The by-election writ was moved in the Dáil on 7 November 2019.[3][4]
Three of the candidates were sitting Wexford County Councillors; Malcolm Byrne, Jim Codd and George Lawlor. Johnny Mythen was a former Wexford County Councillor while Melissa O'Neill was a former Kilkenny County Councillor.
This was the first occasion the Irish Freedom Party contested any national election as a registered political party and, alongside Cork North-Central, the first time Aontú contested by-elections.
Byrne subsequently lost his seat at the February 2020 general election. His defeat after only 71 days made him the TD with the second-shortest term of service.[7] Byrne was subsequently elected to the Seanad in April 2020, with Mythen and Murphy being elected to the Dáil in the 2020 general election.[8]
