Tengku Razaleigh Hamzah
The Pan-Malaysian Islamic Party (PAS) withdrew from BN in the midst of the 1977 Kelantan Emergency over disagreements with UMNO over the running of the state government of Kelantan, which PAS had controlled since the first post-independence general election in 1959. With the support of UMNO, detractors within PAS split with the party and formed the Pan-Malaysian Islamic Front (BERJASA). In the election, PAS lost the control of the state for the first time to the UMNO-BERJASA alliance within BN. Tengku Razaleigh Hamzah has been credited for UMNO's victory in Kelantan.
