Manila, June 5 (IANS): Philippines' president-elect Rodrigo Duterte has ordered three "corrupt" high-ranking officials to step down or be humiliated.

Speaking to around 200,000 supporters at the so-called "thanksgiving" party on Saturday, the tough-talking former Davao city mayor demanded the resignation of the three unnamed Philippine National Police (PNP) officials, whom he said are based at the national headquarters of Camp Crame and have been involved in corruption.

"Corruption must stop," Duterte said, adding "Do not wait for me to name you in public because I will only humiliate you."

Supporters of the incoming president began making their way to Davao city's Crocodile Farm on Saturday for the party, which started at 1.00 p.m. and stretched into the early hours of Sunday.

Many attendees also enjoyed snacking on roasted crocodile, which the park is famed for.

Duterte, who won a landslide victory in the May 9 elections, has pledged to wipe out crime and corruption in the country in six months.

He won the confidence of many voters with his achievement of changing Davao from one of the country's most dangerous cities to one of its safest.
