MANILA, Philippines — Senator Robinhood Padilla has proposed amending the 1987 Constitution and allowing the president and vice president to serve for four years and two terms.

Under his Resolution of Both Houses (RBH) No. 5, the president and vice president would be elected “joint candidates,” the Senate would grow to 54 members, with 24 of them serving for eight years, and the House of Representatives lawmakers would serve for four years.
