The fourteenth election to Glamorgan County Council, south Wales, took place in March 1931.
Labour was defending a secure majority in an election where they faced opposition from the left in the form of the Communist Party, as well as more traditional opponents.
In the Cymmer ward, David Thomas, who had failed to hold the seat in 1928 after David Watts-Morgan was elected alderman, was successful after the sitting Independent stood down.
Howell, switched to contest the Porthcawl ward and Labour won the seat.
Following the 1931 election, there were eleven Aldermanic vacancies, and the retiring aldermen were all re-elected.
