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. The result showed little change from previous years.
Labour retains its majority.[2] The party won some additional seats, such as Pentre in the Rhondda where T.A. Thomas had held on against several previous Labour challenges.
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.
In addition to the 66 councillors the council consisted of 22 county aldermen. Aldermen were elected by the council, and served a six-year term. Following the 1931 election, there were eleven Aldermanic vacancies, and the retiring aldermen were all re-elected.[3]
The following retiring aldermen were re-elected:
William Bowen (Lab, Llanfabon)
David Daniel Davies (Lab, Pontardawe)
Rose Davies (Lab, Aberaman)
John Evans (Lab, Maesteg)
Johnson Dicks (Lab, Abercynon)
E.H. Fleming (Lab, Hopkinstown)
William Jenkins (Lab, Glyncorrwg)
Caradoc Jones (Lab, Llandeilo Talybont)
David Lewis (Lab, Tylorstown)
John Thomas (Lab, Port Talbot)
Rev D.H. Williams (Ind, Barry)
