MANILA—President Rodrigo Duterte's State of the Nation Address on Monday will reflect "how the future will look like" in the country, Presidential Communications Secretary Martin Andanar said Saturday.

"This Monday will be the day that you will know the future and how the future will look like in the Philippines," Andanar told state-run Radyo ng Pilipinas in an interview.

Andanar emphasized that the upcoming Presidential annual address, Duterte's 4th, will be one of the most important SONAs of the chief executive as it will revolve around his "legacy."

"Ito basically ang isa sa pinaka-importanteng SONA ni Presidente . . . this is about legacy building. I call it the Duterte legacy," said the communications head.

The "Duterte legacy" for the next 3 years, according to Andanar, will address the issues of poverty alleviation, infrastructure, and peace and order.

"Those are the three that will be the overarching message for the next 3 years, those are the 3 that we call the Duterte legacy," Andanar said.

Malacañang earlier said that Duterte will likely focus on his 2016 campaign issues such as the war on drugs, crime and corruption in his upcoming speech.

Andanar revealed that Duterte's speech for Monday is "98%" done as it still has room for corrections.

He said the President's annual address might take 45 minutes to 1 hour and 20 minutes, depending on Duterte.

"‘Pag nag-ad lib [siya], mas mahaba," Andanar said.
