Based upon agreements reached with the president, seven of its MPs were due to submit the proposal, as mentioned in the agenda.
But, Mayantha Dissanayake told parliament that they decided against tabling it.
The adjournment debate took place in the absence of UPFA MPs, who continue to boycott the sittings.
Later, speaking to BBC Sinhala Service, UNP’s Ajith P. Perera said it was pointless to submit their proposal in light of the fact that the president was not fulfilling his promises.
He said the UNP has not decided to move an impeachment motion against the president, as mentioned by his colleague Mangala Samaraweera.
Perera reiterated that the UNP would not name anyone else, other than Ranil Wickremesinghe, to the position of prime minister.
The JVP too, strongly criticized the conduct of the president, with its MP Vijitha Herath telling the adjournment debate that it was futile to discuss the matter with the president further.
Time has come to decide if a person like him should remain as the country’s leader, after he violated the constitution many times, said Herath.
According to him, the proposal that was to be tabled in the House today was one prepared by president Sirisena with the intention of getting the proposals mentioned against him in the first no-confidence motion dropped.
The president wants to save himself and bring in a proposal against , he charged.
The president has repeatedly asked UNF leaders to drop those proposals which claim the presidential orders to appoint Rajapaksa as the PM were unconstitutional.
Those proposals could be used against him in an impeachment motion, president Sirisena has told the foreign media.
