“Matagal na naming pinaguusapan yun bago pa maghalalan ng 2013,” said Binay.
Binay, who has declared his intention to run for president in the May 2016 elections, also confirmed that Batangas Governor Vilma Santos and Senator Jinggoy Estrada are among his potential vice presidential candidates.
Binay has cut ties with the Partido Demokratiko ng Pilipinas (PDP)-Laban to launch a new political party that will carry him as its presidential standard-bearer.
He said he will announce the name of his new political party on June 12, Independence Day.
Binay said his new political party will still coalesce with the United National Alliance (UNA), where he ran and won as vice president in the 2010 elections.
Pacquiao, however, said he has yet to make a final decision on Binay’s offer.
“Kung mabuo talaga ang desisyon ko na tumakbo sa Senado e magkapartido naman kami eh,” he said.
The Filipino boxing superstar said he has to consider the welfare of his family in General Santos City.
“’Yung responsibility ko sa pamilya… ako naman ang inaasahan ng lahat eh,” said Pacquiao. -- Reports from Alvin Elchico, ABS-CBN News; Zhander Cayabyab, dzMM; Jay Dayupay, ABS-CBN General Santos
