[28] Ellie Kisyombe, a Malawi-born refugee running for the Social Democrats in Dublin's North Inner City LEA, was retained after a review of inconsistencies in her account of her asylum history and time in direct provision, which caused several party members to resign in protest.

[30] Taoiseach Leo Varadkar stated after the poll that news of a personal injury claim taken by Fine Gael TD Maria Bailey in the week preceding the elections had caused reputational damage to Fine Gael.

[31] Republican Sinn Féin and Independent Left are not registered parties; therefore their candidates appear on the ballot as Non-Party.
