The United National Party, together with its coalition partners within the UNF alliance submitted a motion today to suspend Mahinda Rajapaksa's expenditures.
The motion would see staff salaries and other costs taken away from his budget.
The motion is expected to be debated on November 29.
The TNA spokesperson, M A Sumanthiran and Anura Kumara Dissanayake, the JVP leader and Chief Opposition Whip, have said they will support the motion.
Sri Lanka has been in turmoil for weeks after Rajapaksa was appointed as prime minister by President Sirisena following the shock sacking of the premier Ranil Wickremesinghe.
Last week parliament descended into violence with MPs throwing chairs and chilli water at each other and at the police. A UNP MP was seen wielding a knife and another MP was seen slapping a police officer.
