In 1959 British Honduras undertook another constitutional review, headed by Sir Hillary Blood. Blood's report served as the basis for a constitutional conference in London in 1960 and for reforms that took effect in March 1961. As a result of the review, the composition of the Legislative Assembly and Executive Council changed. In the twenty-five-member assembly, eighteen members were now to be elected from single-member districts, five were to be appointed by the governor (three of these after consultation with the majority and minority party leaders), and two were to be official members. Assembly members served a term of four years.

The eight-member Executive Council included the assembly's majority-party leader, whom the governor appointed as first minister. Two council members were to be official members, and five unofficial members were to be elected by the assembly. Five ministerial posts, including that of first minister, carried portfolios.
