MANILA- Both Communist Party of the Philippines (CPP) founding chairman Jose Maria Sison and the Magdalo group denied Tuesday that they were in cahoots to oust President Rodrigo Duterte.

This, after the President alleged that the communist leader is conniving with the Magdalo group.

Duterte said he has evidence to support his claim as provided by a foreign country “sympathetic” to him.

"I just would like to say categorically that we don't connive with the communists," Magdalo Party-list Rep. Gary Alejano told ANC Tuesday.

"It's very far in our minds to connive and cooperate with the communists in this country," he added.

Duterte over the weekend urged the public to watch out for his critics' supposed move to oust him, which he said will "go into high gear" in October.

"Duterte is now worried to death and so desperate as to imagine that he would be posed this coming October," Sison said in a statement.

Sison meanwhile denied any supposed ouster plot against Duterte but noted that the CPP "wishes to promote a broad united front of patriotic forces" to "rise up and oust Duterte."

"There has never been any discussion between me or the CPP with Trillanes or the Liberal Party about ousting Duterte from power," he said.

"The moment of ouster will occur when Duterte´s own military and police forces withdraw support from Duterte upon the sight and inspiration of the rising people in their millions throughout the archipelago," he added.

Sison also renewed his claims of the President's "deteriorating physical and mental health manifested by his much-darkened face and insane statements," which have repeatedly been dismissed by Malacañang.
