Jagan's veto of British Guiana's participation in the West Indies Federation resulted in the complete loss of Afro-Guyanese support. In the late 1950s, the British Caribbean colonies had been actively negotiating establishment of a West Indies Federation. The PPP had pledged to work for the eventual political union of British Guiana with the Caribbean territories. The Indo-Guyanese, who constituted a majority in Guyana, were apprehensive of becoming part of a federation in which they would be outnumbered by people of African descent. Jagan's veto of the federation caused his party to lose all significant Afro-Guyanese support.
