MANILA - In just two days, two contradicting statements were issued by the camp of presidential aspirant Davao City Mayor Rodrigo Duterte.

This is in connection with the existence of a bank account supposedly containing over P200 million not declared in the mayor's Statement of Assets, Liabilities and Net worth (SALN).

More than a month ago, Duterte challenged his rivals to open their bank accounts to scrutiny so as to inform voters of the kind of candidates they are supporting.

However, with the new allegations being trumpeted by Senator Antonio Trillanes IV, the tough-talking mayor now seems to be singing a different tune.

Speaking to reporters in Tacloban City, running mates Davao City Mayor Rodrigo Duterte and Senator Alan Peter Cayetano signed a manifesto urging other presidential and vice presidential candidates to execute a waiver on the Bank Secrecy Law.

Duterte and Cayetano challenged other candidates to open their bank accounts to scrutiny so voters would know what kind of candidate they are supporting.

In April 25, 2013, vice presidential candidate Chiz Escudero executed a bank secrecy waiver exclusively in favor of the Office of the Ombudsman.

On the morning of April 27, Senator Antonio Trillanes IV alleged that Duterte was keeping P211 million in a joint account with his daughter, Sara, at the BPI branch on Julia Vargas Avenue in Pasig City.

"We are talking about somebody running for president who is pretending to be poor, but it turns out that he is a fraud," said Trillanes, who cited his "network of informants" for the information on the alleged account.

In the afternoon, Duterte called on the public not to believe the words of Trillanes, insisting that the senator's allegations are "pure garbage."

"I am not a rich man," Duterte said before members of the business community where he was set to bare his economic platform.

"What I have is P200,000. Puro kabalastugan yan. Trillanes, he is a dangerous man. Kita mo ang porma maglakad, akala mo kung sino ang buang (crazy)," he added.

In an interview on ANC's "Headstart" Thursday morning, Duterte's spokesperson, Peter Laviña, denied the existence of the BPI account, calling it a mere fabrication by Trillanes as part of a "smear campaign" against the PDP-Laban standard bearer.

"This is a non-existent account. As a lawyer, he would not issue any waiver pointing to a non-existent account," Laviña said, adding that the burden of proof is with Trillanes.

Past 2 p.m., however, journalist Ellen Tordesillas posted on her Facebook account a photo of a deposit slip which proves that a joint account of Duterte and his daughter at BPI exists.

"A friend went to BPI an hour ago to find out if the expose of Sen. Trillanes on Duterte's account is true. Using the bank account number she saw in the Inquirer, she deposited P500. It's validated. The account is existing. Here's the deposit slip," Tordesillas said in her post.

After the proof surfaced on social media, Duterte admitted that the account at the BPI branch on Julia Vargas does exist. He, however, insisted that the account does not contain P211 million.

Speaking to reporters in Bataan, Duterte said he has several bank accounts, but none of these contain millions. He said two of his accounts contain only P17,000 and P50,000 each.

"Meron ako sa BPI. Hindi ganun kalaki. Thousands lang. It could not go beyond even... Meron isa 17 (thousand), yung isa below 50 (thousand)," he said.

Duterte also denied that the account is a joint account with his daughter, Sara.

Amid calls for Duterte to sign a bank secrecy waiver, rival presidential candidate Mar Roxas executed a waiver in favor of the Office of the Ombudsman to obtain information not only on his bank accounts but other documents as well, including those from the Bureau of Internal Revenue (BIR).
