The impeachment complaint filed against President Rodrigo Duterte "seems like part of a bigger scheme" as it "outlines" the destabilization against the government, presidential spokesperson Ernesto Abella said Thursday.

Minutes prior Abella's statement, Magdalo Party-list Rep. Gary Alejano filed an impeachment complaint against Duterte at the House of Representatives and accused the President of culpable violation of the Constitution, betrayal of public trust, graft and corruption, bribery and other high crimes in relation to the government's war on drugs.

"Events like these seem to be too coordinated than it is coincidental... with acts of trying to discredit the admin, trying to throw it in doubt," Abella told Palace reporters.

Abella said the President "is ready for the consequences of his actions" and will "uphold due process."

"Hayaan sila magsalita, habulin gusto nila mangyari," he added.

The spokesman also denied allegations the chief executive will rally its legislative allies to shoot down the impeachment complaint.

"The president always allows his allies to act independently of him. He is not manipulative... He has always respected the independence of his colleagues," he said.
