In a tweet Thursday's afternoon, Trillanes said he was also running for senator under Robredo's slate, amid speculations that he would be the vice president's 2022 running mate.

Trillanes and Robredo battled it out in the 2016 elections but has since become allies against the drug war and China policy of President Rodrigo Duterte.

Robredo, the opposition leader picked by coalition 1Sambayan as its presidential bet, cited the crucial need for decent leadership and immediate action to stop the pandemic.

"Buong buo ang loob ko ngayon. Kailangan nating palayain ang sarili mula sa kasalukuyang sitwasyon. Lalaban ako. Lalaban tayo. Inihahain ko ang aking sarili bilang kandito sa pagkapangulo sa halalan ng 2022," Robredo said in a speech at her Quezon City office.
