On February 15, 2007, the group changed its name again to Genuine Opposition after a meeting with Senate President Manny Villar due to the defection of senators Edgardo Angara, Tessie Aquino-Oreta, and Tito Sotto to Arroyo's senatorial slate, TEAM Unity.

They gained one more seat in 2011 after an electoral protest, through which GO's Koko Pimentel replaced TEAM Unity's Migz Zubiri.

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 name again to "Genuine Opposition" (GO) after a meeting with Senate President Manny Villar in his office in Las Piñas.

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.
