Former President Joseph Estrada, speaking at the book launch of Juan Ponce Enrile's autobiography, said the Senate President can be a good friend but is a tough enemy.
"Hindi ko alam bakit may iba diyan na pinipili siyang kalabanin nang walang pakundangan," Estrada said. "(Siya ay) mabait na kaibigan pero mabigat na kalaban."
Enrile recently had a spat with Senator Antonio Trillanes IV over the Camarines Sur bill and Trillanes' diplomatic talks with China over Scarborough Shoal.
Estrada said many personalities in the Philippine political scene have written their own roles in history "but Manong Johnny has kept his silence for a long time."
"Manong Johnny owes his life story not only to himself and his family but also to the nation, future generation," he added. - ANC
