The president filed withdrawal papers with the election commission hours after his longtime aide Senator Christopher “Bong Go” did the same, a decision Duterte’s spokesman said was to allow him to serve better the country.
He had planned to continue as vice-president, but instead chose to run for a seat in the powerful senate.
The pullout is the latest twist in a Filipino election race full of last-minute changes and surprises that have baffled political experts.
Go did not perform well in opinion polls and it is unclear who will have the approval of Duterte, who has maintained a consistently high approval rating since winning the 2016 election as foreigner promising to fight crime and drugs.
