MANILA, Aug. 24 (Xinhua) -- Philippine President Rodrigo Duterte, whose single six-year term ends next year, has accepted the ruling political party's endorsement to run for vice president in the 2022 elections, Cabinet Secretary Karlo Nograles said on Tuesday.

Duterte "agreed to make the sacrifice and heed to the clamor of the PDP-Laban party for him to run as vice president in the 2022 national elections," Nograles, the executive vice president of the governing PDP-Laban party, said in a statement.

Nograles said Duterte accepted the endorsement "after (being) presented with popular calls" from PDP-Laban's members "aspiring for a transition of leadership that will guarantee continuity of the administration's program during the past five years" of Duterte's administration.

Nograles said the party will discuss Duterte's nomination during their national convention next month.

Duterte, 76, was elected president in the May 2016 elections. The constitution limits Philippine presidents to a single six-year term.

The vice president is elected separately from the president under the Philippine law. The vice president can be propelled to the presidency if the president dies or is incapacitated.

Neither Duterte nor his spokesperson has yet to issue an official statement on the endorsement.
