Merv Toms had held Ascot for the Labor Party since the seat's creation at the
1968 state election, and had first been elected to parliament at the
1956 election. He was elected to the speakership after Labor's victory at the
1971 election, and due to the party's one-seat majority had to frequently exercise his
casting vote. Toms died in office on 8 October 1971, with the writ for the by-election issued on 14 October and the close of nominations on 21 October. Polling day was on 13 November, with the writ returned on 30 November. ==Results==
