The younger Hughes was educated at the University of Cambridge, where he gained a First Class Honours degree in Law.
A pacifist and Liberal party supporter, he followed his son"s switch in political allegiance to Labour. His family moved to Birkenhead in 1917, and Hughes was elected there as a local councillor. At the 1929 general election, he stood as a Liberal candidate in the safe Labour Party-held constituency of Rhondda West, losing heavily to the sitting Labour Member of Parliament William John.
In October 1930 he was chosen as Liberal candidate for the more winnable Southport seat but at the 1931 General Election, he was well beaten by the Conservative candidate.
Soon after Hughes joined the Labour Party, and stood unuccessfully as the Labour candidate in the Cardiganshire constituency at the 1935 general election. However, at the 1945 general election, he lost the seat by 1,279 votes to the Liberal candidate Rhys Hopkin Morris.
Hughes returned to Parliament at the 1950 general election, when he was elected as (Member of Parliament) for the safe Labour seat of Islington North, in North London. He represented the constituency for only one year, until he stepped down at the 1951 general election.
