On the evening of November 13, 2007, an explosion[1] at the South Wing of the Batasang Pambansa Complex killed six people, including Rep. Wahab Akbar (Lakas-CMD, Basilan).

On November 4, the House Committee on Justice, dominated by pro-Arroyo lawmakers, declared as "sufficient in form" the three-page impeachment complaint against President Arroyo.

Detained Senator Antonio Trillanes IV, General Lim and other Magdalo (mutineers) officials walked out of their trial and marched through the streets of Makati, calling for the ouster of President Gloria Macapagal Arroyo, and seizing the second floor of The Peninsula Manila Hotel along Ayala Avenue.

Sen. Antonio Trillanes IV and Brigadier Gen. Danilo Lim surrendered to authorities after an armored personnel carrier rammed into the lobby of the hotel.

Days after the mutiny, the Makati Regional Trial Court dismissed the rebellion charges against all 14 civilians involved in the siege, and ordered their release.

It has also taken an interesting turn of events, including the resignation of Abalos as COMELEC chairman, the alleged bribery of congressmen and provincial governors (dubbed as "Bribery in the Palace"), the unseating of Jose de Venecia, Jr. as House Speaker, and the alleged "kidnapping" of designated National Economic and Development Authority (NEDA) consultant-turned-NBN/ZTE witness Rodolfo Noel "Jun" Lozada, Jr.
