# 1928 Glamorgan County Council election

The thirteenth election to Glamorgan County Council, south Wales, took place in March 1928. It was preceded by the 1925 election and followed by the 1931 election.

## Overview of the Result

Labour was defending a secure majority in an election that was more bitterly fought than in previous year, in the wake of divisions persisting after the General Strike and lockout of 1926. Non-Labour candidates largely coalesced under an Independent banner but lost further ground as Labour won additional seats

## Boundary Changes

There were no boundary changes at this election.

## Candidates

20 candidates were returned unopposed, only five won whom were Labour.
Following the death of Dr T.H. Morris (Rhondda) there were ten retiring aldermen, nine of whom sought re-election. The only exception was Thomas Luther Davies (Aberaman).

## Contested Elections

The pattern of contests was similar to 1925, although Labour did challenge some long-serving aldermen including W.R. Davies (first elected in 1898) at Cilfynydd and Enoch Davies in the Rhondda. In the Garw Valley ward, retiring alderman Rev. William Saunders was opposed by the sitting Independent councillor as was Alderman D.T. Williams in the Swansea Valley ward.

## Outcome

Labour gained a number of seats, increasing their majority on the County Council.
A notable result in the Dulais Valley was the defeat of coal owner Daniel Daniels, former chairman of the Council, by Labour candidate Gwilym Davies. Daniels had not been re-elected as an alderman three years previously and the result came after a series of disputes in the mining industry.
In the Cilfynydd ward, Labour candidate Arthur Pearson defeated Alderman W.R. Davies, first elected to the council in 1898. Labour had won the seat in 1919 but in 1922 stood down to allow Davies to be returned unopposed. The decision to oppose him reflected the increasingly partisan politics of the mining valleys and Davies was narrowly defeated.
A similar situation arose in Treherbert, a seat won for Labour by D.E. Williams in 1919. Williams stood down in favour of Alderman Enoch Davies in 1922 but having been returned unopposed in 1925 he stood against Davies and was returned by several hundred votes. Enoch Davies had served as a member of the Council since 1901, and was a prominent tradesman and nonconformist.
Labour lost only two seats, at Penygraig in the Rhondda and also Pontardawe. The latter was significant as it was also represented by Alderman Dan Dai Davies, jailed for his role in the anthracite strike and disturbances of 1925. Labour consolidated their majorities in many others, including seats gained three years previously.
