It was first elected to power in 1932 on a constitutional republican platform, promising to remove constitutional links with Britain and reduce poverty by creating employment. It oversaw much of the industrial development of the Republic and has consequently drawn support from all social classes, making it a classic populist party.[6][7][8]
