MANILA - The Commission on Elections (Comelec) will resolve disputes within political parties next week, poll body chief Sheriff Abas said Friday.

Folk singer Freddie Aguilar on Thursday filed a certificate of candidacy under the breakaway faction of the Partido Demokratiko Pilipino-Lakas ng Bayan.

The Comelec has yet to identify which wing of President Rodrigo Duterte's party should be deemed as the legitimate group, Abas told reporters on the second day of filing of candidacy.

Executive sessions will be held on October 18 to sort out legitimate political parties from breakaway factions, Abas said.

"Ang mga intra-party [issues] kailangan talaga ng notice and hearing," he said.

"Ang commitment namin, after ng hearing, pabibilisin namin ang decision para hindi ma-confuse mga kandidato," he said.

Candidates who belong to groups deemed as "breakaway" would become independent candidates, said Comelec Law Department Dir. Maria Norina Tangaro-Casingal.

"A political party is only entitled to nominate only the number of positions to be voted for," Casingal said.

"For example, sa senators 12 lang dapat. If 2 wing mag-field ng tig-12, all of them would be declared as independent candidates," she said.

"We have to determine who are the real members," she said.
