MANILA (UPDATED) - Vice President Leni Robredo said on Tuesday she did not regret speaking about President Rodrigo Duterte's war on drugs before a United Nations (UN) body.

Robredo's videotaped message to a side event of the UN Commission on Narcotic Drugs has sparked calls for her impeachment.

"Hindi ako nagsisisi kasi bago ko naman ginawa yung statement na yun, pinagaralan. Hindi naman yun yung parang bigla mo lang inisip tapos sinabi mo," Robredo said during an interview with DZMM on Tuesday morning.

(I have no regrets because I studied that statement before I delivered it. It was not drafted on a whim.)

Robredo said she did not tell the UN that all 7,000 killings since Duterte took office were drug-related, refuting claims by the police leadership.

"Wala akong sinabi na yun yung drug-related. Ang sabi ko lang, from the time na ni-launch yung anti-drug war, nagkaroon na tayo ng 7,000 summary executions," Robredo said.

(I did not say that they were drug-related. What I said was, from the time the drug war was launched, there have been 7,000 summary executions.)

She said it was not the first time that the figures were reported. Police numbers also don't add up, she added.

Citing an earlier report by the PNP, Robredo said only 3, 979 were drug-related deaths while 3,560 were classified as deaths under investigation (DUI).

"Kahit hindi pa siguradong drug-related ito, si Gen. Bato [Ronald dela Rosa] na mismo nagsabi na parang sumakay ito sa anti-drug war," she said,

In her video, Robredo also revealed an alleged "palit-ulo" scheme wherein authorities would take a family member in case a suspect on the drug list could not be found.

"Noong tinitira akong walang basehan yung aking sinasabi, ang pinaka-instinct ko sana depensahan ang sarili ko na totoong may nagsusumbong ng palit-ulo. Pero di ko pa pwedeng ilabas sila kasi natatakot," she said.

(When I was criticized without basis, my instinct told me to defend myself because there have been reports of palit-ulo. But I could not reveal their identities because they are scared.)

But she’s ready to disclose them once the meeting with Department of Interior and Local Government (DILG) Secretary Ismael Sueno pushes through. The vice president met with Sueno during the PNPA Graduation ceremony last week.

"Ibibigay ko sa kanya yung detalye. Hopefully, itong paglapit natin sa DILG para mabigyan sila ng assurance kasi ayaw talaga nilang lumapit sa pulis," she said.

(I will give him the details. Hopefully, this meeting with the DILG will give them reassurance they need because they really do not want to approach the police.)

Aside from "palit-ulo," Robredo said her office received complaints of illegal searches, and planting of evidence from poor communities.
