Peru's President Alejandro Toledo says he will open his personal bank accounts to scrutiny in an attempt to counter allegations of corruption.
Mr Toledo's approval ratings have plummeted to single digits
Mr Toledo said he had written to regulators requesting a review of his "personal and conjugal wealth".
"Peru needs to regain confidence in its leaders," he said, urging lawmakers and regional politicians to do the same.
Mr Toledo's popularity has been hit by a series of allegations concerning himself and his family.
His approval rating now languishes in the single digits - making him the least popular head of state in Latin America.
String of claims
Mr Toledo's comments, made during a speech marking his third anniversary in office, came two days after damaging fresh allegations in Peru's top news magazine, Caretas.
It said a former presidential adviser, Cesar Almeyda, told one of its reporters that the president took a $5m bribe from a foreign company - allegations swiftly denied by both Mr Toledo and Mr Almeyda.
The claims continued to mount on Wednesday, with newspapers reporting that a state attorney had asked for a travel ban to be imposed on first lady Eliane Karp, amid allegations she misused funds from the World Bank.
On the same day, a judge imposed a temporary travel ban on Mr Toledo's youngest brother, Pedro.
He is accused, along with four others, of committing fraud while setting up a telephone company.
Last week the president's sister Margarita was summoned by a state prosecutor as part of investigations into an alleged signature-forging ring. She has denied any involvement in the case.
The president is also trying to rebuild his credibility after losing several ministers in corruption scandals.
