(PNA File photo) MANILA - For the first time in the history of the 60-year-old Caloocan City in northern Metro Manila, its residents of over 1.5 million will be electing three representatives to Congress in the May 9, 2022 polls. This is because Republic Act (RA) No. 11545, enacted by the 18th Congress and signed into law by President Rodrigo R. Duterte on May 26, 2021, will be implemented by the Commission on Elections (Comelec) this year. RA 11545 increased the number of Caloocan City's congressional districts from two to three by reapportioning the populous District 1 or North Caloocan. The original District 1, composed of Caloocan barangays located north of Epifanio Delos Santos Avenue (EDSA), was divided into two districts. Eleven big and very populous barangays, including Bagong Silang, were segregated to form the third district. The rest of the barangays remain in District 1. Caloocan, a former town of Rizal province, used to be part of the first district of Rizal from 1907.
