1946 Glamorgan County Council election

Labour's comfortable majority on the council, including the aldermanic bench, remained unchanged.

There were no boundary changes at this election.

A significant number of Labour candidates were returned unopposed. A number of long-standing members stood down including the Reverend William Saunders, who was not selected as a Labour candidate and Gwilym Davies (Dulais Valley).

There was significant Communist opposition, particularly in the Rhondda where Labour had only narrowly retained the Rhondda West constituency at the previous year's General Election.

In Neath, it was originally reposed that long-serving councillor D.G. Davies, who had been a member of the county council with a few breaks foe twenty-five years, would stand again.[1] However, he ultimately stood down.

Nine of the retiring aldermen sought re-election, the exceptions being the Rev William Saunders and Edgar Chappell.

Labour retained their majority. In the Rhondda Valley, Labour withstood a Communist challenge[2] This was the first county election for nine years as polling was reported as heavy in a number of wards, including the two contested wards at Pontypridd.[3]

In the Neath area, Labour retained four seats but at Coedffranc the sitting member D.T. Jenkins was defeated by Communist Alun Thomas, a member of the Neath Rural council since 1937.[4]

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 1946 election, there were eleven Aldermanic vacancies, all of which all of which were filled by Labour nominees despite the protestations of their opponents.[5] Rhys Evans was the longest serving alderman, having first been elected in 1922.

The following retiring aldermen were re-elected:

• Sidney Cadogan (Lab, Ystrad)
• W.H. Davies (Lab, Gower)
• Alfred Evans (Lab, Ferndale)
• Rhys Evans (Lab, Treorchy)
• Tom Evans (Lab, Pengam)
• Daniel T. Jones (Lab, Ystalyfera)
• W. Arthur Jones (Lab, Tonyrefail)
• Evan Phillips (Lab, Caerphilly)
• Rev W. Degwel Thomas (Lab, Neath)

The following new aldermen were elected:

• H.J. Cook (Lab, Penarth)
• Mervyn Payne (Lab, Pencoed)

Eleven vacancies were caused by the election of aldermen. At Neath, Charles P. Huins held his seat with a majority whip exceeded that gained by Alderman Degwel Thomas at the triennial election.[6]
