Genuine Opposition (GO) is the political multi-party electoral alliance of the parties' senatorial line-up for the 2007 Philippine midterm elections, which is in opposition to President Gloria Macapagal-Arroyo. It was originally called the "United Opposition" (UNO), created by opposition stalwart and Makati City Mayor Jejomar Binay on June 2005 to unite all politicians who wanted to impeach President Gloria Macapagal-Arroyo. UNO then reorganized itself and changed its name to Grand and Broad Coalition (GBC), with the UNO party under that coalition. On February 15, 2007 the group changed its name again to Genuine Opposition after a meeting with Senate President Manny Villar in his office in Las Piñas City.
Mainstream party members
The United Opposition Coalition was created by Makati City Mayor Jejomar Binay on June 2005 to unite all politicians who wished to impeach Philippine President Gloria Macapagal Arroyo. The UNO started scouting candidates for the Senate as early as October 2006 to claim a large share of the Senate seats. On January 2007, UNO started short-listing its nominees after a large number of interested personalities wanted to join the opposition. The UNO changed its name on February 12, 2007 at the Club Filipino in San Juan, Metro Manila to "Grand and Broad Coalition" (GBC). On February 15, 2007 the group changed its named again to "Genuine Opposition" (GO) after a meeting with Senate President Manny Villar in his office in Las Piñas. GO became the opposition coalition with eight parties under its wing, including its predecessor, UNO. Though Senate President Manny Villar and Senate Majority Leader Francis Pangilinan are running under the Opposition, they remain independent candidates as in the 2001 election. On February 28, 2007, Genuine Opposition dropped Kiko Pangilinan as its adopted candidate. After the elections, GO reverted to being the United Opposition, with Binay as head, but still maintaining the support of the other parties that comprised GO.
