Louis J. Belton (30 November 1943 – 11 November 2023) was an Irish Fine Gael politician from Kenagh,[1] County Longford,[2] and the seventh member of the Belton family to be elected to the Oireachtas.
Formerly a building society employee, Belton was a member of Longford County Council from 1979 to 1999.[3] He was elected to Dáil Éireann at the 1989 general election as Teachta Dála (TD) for the Longford–Westmeath constituency, but lost his seat at the 1992 general election when contesting the revised Longford–Roscommon constituency.
However, he was then elected to the 20th Seanad in 1993, when he topped the poll for the Administrative Panel. He regained his Dáil seat at the 1997 general election but lost it again at the 2002 general election to Mae Sexton of the Progressive Democrats. He did not contest the 2007 general election. His brother Patrick was a county councillor and Mayor of Longford.[3]
Belton died at the Midland Regional Hospital, Mullingar on 11 November 2023, aged 79.[4] [5]
