Romanian anti-corruption prosecutors said on Friday they had launched a criminal investigation against Prime Minister Victor Ponta, naming him as a suspect in crimes including forgery, money-laundering, conflict of interest and tax evasion.
Local media showed Ponta entering the anti-corruption prosecutor's office on Friday morning.
Prosecutors have made a series of high-profile arrests in recent months in what remains one of the poorest and most graft-addled countries in the European Union. The anti-corruption agency is known locally as the DNA.
"I came to the DNA like a normal person," Ponta told reporters. "I didn't give them any statement." Asked whether he would resign, he said: "At the DNA, we don't do politics."
