Philippine Vice President Sara Duterte resigned on Wednesday from the Cabinet of President Ferdinand Marcos Jr. and another key post — an unsurprising move given her alliance with Marcos had long been expected to crumble.

Marcos has accepted Duterte's resignation from the posts of education minister and vice chair of an anti-insurgency task force, Presidential Communications Secretary Cheloy Garafil said in a statement, adding that no reasons were given by her for stepping down.

Duterte, who will remain vice president, said in a press conference that her "resignation is not because of weakness, but because of true concern for teachers and the youth."
