THE country is slowly headed toward a constitutional crisis, Senate President Juan Miguel Zubiri had warned as the bickering among lawmakers took a turn for the worse on Saturday when a member of the House of Representatives accused 'some senators' of undermining the integrity of Speaker Ferdinand Martin Romualdez.

Zubiri said the Senate had warned about a possible constitutional crisis when the House led a people's initiative campaign to amend the 1987 charter that would have allowed both Houses to vote together as a constituent assembly instead of separately.
