The Philippine Senate resumed work after a senator aligned with Vice President Sara Duterte's bloc broke ranks, enabling rival senators aligned with President Ferdinand Marcos Jr. to secure a 12-member quorum, elect an acting Senate president and reorganize the chamber's leadership, Reuters reported on June 3. Meanwhile, Marcos said the government may need new legislation, including a supplemental budget, to cushion the impact of the country's ongoing oil shock, Bloomberg reported separately on June 3.

The Duterte bloc initially had a Senate majority of 13 members, but the June 1 arrest and continuing absence of two pro-Duterte senators reduced the majority to an effective 11-11 split. After the Duterte-aligned senator broke ranks on June 3, the count is now 12-10 in favor of the Marcos bloc.
