The oppositon is planning to file a motion of no confidence in the Prime Minister, Peter O'Neill.
In the past three weeks, several senior MPs have defected from Mr O'Neill's governing coalition.
The police commissioner, Gary Baki, told the Post Courier reinforcements will be added to help secure Port Moresby during parliament's sitting.
