This very loose political organisation was most significant for the role it allowed Hall to play in the creation of the Progressive Labour Movement (PLM) in 1968.
Hall served as Deputy Premier of Antigua during the Progressive Labour Movement government of 1971–76, and during that period he was also the first Minister for Agriculture in the state.
His flagship policy was diversification of agriculture away from the archipelago's heavy dependence on sugar exports, and to increase the cultivation of other crops, such as the pineapple.
[2] Hall assumed the leadership of the Progressive Labour Movement for a second time in time for the 1980 general election, due to the electoral defeat and subsequent imprisonment of his predecessor, George Walter, on false corruption charges relating to PLM economic mismanagement.
This oppression diminished the appeal of opposition parties, and Hall left the legislature in 1984, three years after the full independence of Antigua and Barbuda.
