However, the relationship of Abdul Rahman with SUPP started to worsen after 1974 election. In May 1978, a delegation of SUPP leaders led by Stephen Yong tried to persuade the prime minister Hussein Onn to remove Abdul Rahman. However, the plan failed because 1978 election was around the corner. As a result, Abdul Rahman allowed the entry of peninsular-based Democratic Action Party (DAP) into Sarawak in 1978 in order to check the Chinese electoral support towards SUPP. On 28 March 1978, Parti Anak Jati Sarawak (PAJAR) was formed due to dissatisfaction of a number of Malays towards Abdul Rahman's increased tolerance to cronyism and his disregard of the welfare of Malay community.
