Formation of Parti Bumiputera To ensure the domination of Muslim Bumiputra in Sarawak politics, PANAS and BARJASA initiated a plan of merger a few months after the local council elections of Sarawak in 1963. Initially, both parties were willing to dissolve themselves in order to allow United Malays National Organisation to enter Sarawak. However, UMNO was not interested in accepting non-Muslim-Malay bumiputeras as members.
