Llywelyn Williams (22 July 1911 – 4 February 1965) was a Welsh Labour Party politician.
Born in Llanelli, Williams was educated at Llanelli Grammar School and Swansea University, after which he became a Congregational minister. He served at Bethesda from 1936 until 1942, and then in Abertillery until 1946, and finally at the Welsh Tabernacle in Kings Cross.[1]
In November 1950 he was elected as Member of Parliament (MP) for the safe Labour seat of Abertillery in a by-election after the death of sitting MP George Daggar. He was re-elected to the House of Commons at the next four general elections, and died in office, in Newport, in 1965, aged 53.[1]
His daughter, Eryl McNally, was a Labour Member of the European Parliament between 1994 and 2004.
