Glyn Tegai Hughes

In 1950 Hughes was a founding member of Undeb Cymru Fydd an all-party organisation that was created to campaign for a Parliament for Wales. Apart from Hughes, the organisation had support from many other leading Welsh Liberals such as Emrys Roberts and Megan Lloyd George who served as the organisation's President. The campaign strategy involved the collection of a nationwide petition to present to the British parliament. The campaign also involved the holding of public meetings at which Hughes was a regular platform speaker. He was critical of how the organisation was created without any full-time staff and of the way the campaign was launched. Although the petition was signed by 250,000 people he did not think that this truly reflected the degree of support in Wales for their own parliament and believed that a referendum on the issue in the 1950s would have been lost. The overwhelming majority of Welsh MPs in the 1950s were Labour Party members who opposed the campaign. When the petition was presented to parliament before the 1955 General Election there was also a debate on the issue of creating a Welsh Parliament that was also backed by Liberal Party Leader Clement Davies. However, due to the combined votes of Conservative and Labour MPs, the bill was defeated.[9] He continued his involvement with Undeb Cymru Fydd, serving as its chairman from 1968–70.[10]

He did not contest the 1951 General Election as he was working in Switzerland at the time.[11] He became active in the Liberal party nationally being elected a member of the Liberal Party Council and of the party's national executive.[12] In 1955 he was again Liberal candidate for Denbigh. In Hughes absence, not only had Garner Evans managed to increase his majority, but the Liberals had slipped to third place. Despite starting from third place, Hughes managed to increase the Liberal vote and re-establish the party as the main challenger again;

He served as Chairman of the Liberal Party of Wales.[14] In 1959 he stood as Liberal candidate for the third and final time. During the campaign he was one of the Liberal Party's featured leaders, along with Robin Day and John Arlott in the televised Party Election Broadcast shown on 22 September 1959,[15] speaking predominantly in Welsh to a predominantly English speaking audience. However, his hopes of finally gaining the seat were dashed by the intervention of a Plaid Cymru candidate who split the Welsh nationalist vote;

In 1967 he became a Member of the Welsh Arts Council, serving until 1976. In 1971 he was appointed National Governor for Wales BBC and Chairman of the Broadcasting Council for Wales, serving in these roles until 1979. In 1977 he became Vice-President of the North Wales Arts Association, serving until 1994. In 1980 he became a Member of the Board of the Channel Four Television Company, on which he sat until 1987. In 1981 he became a member of the Welsh Fourth TV Channel Authority, serving util 1987. In 1988 he became Chairman of the Welsh Broadcasting Trust, serving until 1996.[17]
