Metro Manila, Philippines
 — Vice President Sara Duterte has resigned irrevocably as member of the Lakas-Christian Muslim Democrats (Lakas-CMD), dubbed as the ruling political party in the House of Representatives.

Duterte, who serves as the party’s chairperson, said the resignation is effective Friday.

She did not provide a specific reason for her decision to quit the party, but hinted at “powerplay” as the rationale behind it.

“I am here today because of the trust of the Filipino people…This cannot be poisoned by political toxicity or undermined by execrable political powerplay,” Duterte said, without elaborating further.

Last February, Duterte and House Speaker Martin Romualdez—a first cousin of President Ferdinand Marcos Jr.—reassumed their roles as chairman and president of the Lakas-CMB, respectively.

“I am grateful to all the party members for the support that also once demonstrated that unity is possible to advance our shared dreams for our fellow Filipinos and our beloved country,” she said.

Duterte also said her commitment to serve Filipinos remains “immutable.”
