Millions of Filipinos began voting on Monday in a midterm election widely seen as a referendum on the explosive feud between President Ferdinand Marcos and impeached vice-president Sara Duterte.
Workers in the capital, Manila, were busily setting up polling stations on Sunday for a race that will decide more than 18,000 posts, from seats in the House of Representatives to hotly contested municipal offices.
It is the Senate race, however, that carries potentially major implications for 2028âs presidential election.
The 12 senators elected on Monday will form half the jury in a Duterte impeachment trial â tentatively set for July â that could see her permanently barred from public office. In a speech at a rally last week, Duterte said her name, and her familyâs name âhave been dragged through the mudâ. âWho will really benefit if the Duterte family is gone from this world? Not the Filipinos, not the victims of crime, the unemployed, the poor or even the hungry.â
Duterteâs long-simmering feud with former ally Marcos exploded in February when she was impeached by the House for alleged âhigh crimesâ including corruption and an assassination plot against the president. She has denied the allegations, adding that she had presented the assassination plot as a hypothetical scenario.
Barely a month later, her father, former president Rodrigo Duterte, was arrested and flown to the international criminal court (ICC) the same day to face a charge of crimes against humanity over his deadly anti-drugs campaign.
Sara Duterte will need nine votes in the 24-seat Senate to preserve any hope of a future presidential run.
Heading into Monday, seven of the candidates polling in the top 12 were endorsed by Marcos while four were aligned with his vice-president.
Two, including the presidentâs independent-minded sister Imee Marcos, were âadoptedâ as honorary members of the Duterte familyâs PDP-Laban party on Saturday.
The move to add Imee Marcos and television personality Camille Villar to the partyâs slate was intended to add âmore allies to protect the vice-president against impeachmentâ, according to the resolution.
At her final rally in Manila on Thursday, Duterte invoked the spectre of âmassiveâ electoral fraud and once again referred to her fatherâs transfer to the ICC as a âkidnappingâ.
Despite his detention at The Hague, the elder Duterte remains on the ballot in his familyâs southern stronghold of Davao city, where he is seeking to retake his former job as mayor.
At least one local poll is predicting he will win comfortably.
National police in the archipelago nation have been on alert for more than a week, and about 163,000 officers have been deployed to secure polling stations, escort election officials and guard checkpoints.
Thousands more personnel from the military, fire departments and other agencies have been mobilised to keep the peace in a country where battles over hotly contested provincial posts are known to erupt in violence.
A city council hopeful, a polling officer and a village chief are among the at least 16 people police say have been killed in attacks in the run-up to Mondayâs election.
On Saturday, a candidate for municipal councillor was one of two men in an âarmed groupâ killed in a shootout with police and the military in southern Mindanao islandâs autonomous Muslim region, a notorious hotbed of election-related violence.
Farther north, a group of men were arrested the same day at the Cebu airport while transporting 441m pesos (nearly $8m) in cash, a crime under election rules aimed at preventing the exchange of bribes for votes.
Both cases were still under investigation.
