A possible 'Duterte-Duterte' tandem taking over the country's two top government posts is not a case of political dynasty as the people will elect them, an official of regional party Hugpong ng Pagbabago (HNP) said on Wednesday.

HNP spokesman Anthony del Rosario made the statement as critics raise concerns over political dynasty after the release of a Pulse Asia survey that showed Davao City Mayor Sara Duterte-Carpio leading the presidential race with her father President Rodrigo Duterte taking the top spot for the vice-presidential post.
