Allegations that the Philippine presidential election frontrunner had millions of dollars in an undeclared bank account have not been resolved after the accuser confronted the mayor's lawyer at the bank.

Mayor Rodrigo Duterte's lawyer said he had asked that the account be opened to prove the allegations are false but that bank officials told him Monday it would take a week to study the request. The election is scheduled next Monday.

Sen. Antonio Trillanes IV has alleged that Duterte had more than 200 million pesos ($4.2 million) in 2014 in a joint bank account with his daughter that was not publicly declared as required by law.

Duterte has led in public support surveys and it remains to be seen whether the allegation will hurt his popularity.
