In
1957, Ebenezer and Ivy became the first married couple to be elected to a parliament of the
British West Indies. In 1961, upon Saint Vincent and the Grenadines gaining increased autonomy, Joshua became chief minister. He held the additional portfolio of
minister of finance. His PPP saw continued success in subsequent elections. Joshua supported the unsuccessful
Federation of the West Indies. He then travelled to
Barbados for a regional meeting on agricultural problems; a misunderstanding of this sequence of events and Vincentian history by American musician
Eric von Schmidt became the basis for the song "Joshua Gone Barbados". In 1967 the PPP lost their parliamentary majority and Joshua was succeeded by
Robert Milton Cato, leader of the
Saint Vincent Labour Party. He was appointed
leader of the opposition from 1967 to 1972. After the 1972 elections, Joshua was appointed
Deputy Premier and
Minister of Finance in the cabinet of
James Fitz-Allen Mitchell. He resigned in 1974. Joshua remained in parliament, but the PPP began to decline as the
New Democratic Party emerged as political competition. In 1979 the PPP lost all parliamentary representation. Joshua resigned as party leader in 1980, and the party was dissolved in 1984. ==Personal life==
