Metro Manila (CNN Philippines) — Aside from restoring death penalty and imposing curfew, presumptive president Rodrigo Duterte revealed he is also planning to implement a three-child policy.

Talking to reporters early Sunday (May 22), Duterte said this policy will "probably" form part of family planning program under his administration.

Duterte did not expound on this plan, but said he’s pondering about it.

Defending family planning and the three-child policy, the presumptive president even challenged bishops of the Catholic Church to a debate.

Meanwhile, Duterte said he is willing to work with the 17th Congress to make some of his priority policies enacted into law, particularly the imposition of curfew, as well as the liquor and smoking ban, which will be included in his “first orders” once he assumes office on June 30.

Retaining some Aquino programs

Duterte said he is planning to adopt the good economic policies of outgoing President Benigno Aquino III.

According to Duterte, his camp is studying which policies should be continued, but declined to comment on the issue of raising tax.

Duterte vowed to end contractualization, consistent to what he stated in several presidential debates during the campaign.

The incoming president added, like Aquino, he will not use “wang-wang,” [siren sounds] and will not even use the presidential plate number for his vehicles.
