The Sarawak BN has been urged to review its position in the BN coalition on grounds that Prime Minister Najib Abdul Razak is not sincere towards Sarawak's request for its oil and gas royalty payment to be raised to 20 percent.

The call was made today by DAP Member of Parliament for Bandar Kuching, Chong Chieng Jen, who said the BN-dominated Parliament was refusing to discuss his motion to debate the 20 percent oil and gas royalty payment for Sarawak.
