 At the 1922 general election, Emlyn-Jones was elected to Parliament for the constituency of North Dorset and he retained the seat in 1923.In a predominantly rural constituency, one of Emlyn-Jones’ concerns was to represent the interests of agricultural workers.During the first Labour government, Emlyn-Jones pointed out how Labour, supported by the Conservative opposition, was not standing up robustly enough for agricultural labourers by refusing to incorporate this group into a Minimum Wages Bill, which he attempted unsuccessfully to amend.
