The sibling rivalry between Makati mayoral candidates Jejomar Erwin “Junjun” Binay Jr. and reelectionist Mayor Mar-len Abigail “Abby” Binay escalated on Saturday, following a public confrontation inside a church.

Videos making the rounds of social media shows Junjun confronting Abby during a forum hosted by the Parish Pastoral Council for Responsible Voting (PPCRV) at the San Ildefonso Parish in Barangay Pio del Pilar, Makati City.
