Romania's prime minister says he will contest prosecutors' accusations he has engaged in money laundering, forgery and being an accomplice to tax evasion.

Victor Ponta said Sunday the case against him is politically motivated and that he would file a complaint because prosecutors accused him without a formal hearing.

Anti-corruption prosecutors last week said Ponta had entered into contracts with the law firm of a political aide while working as a lawyer in 2007 and 2008 and made expense claims which were not related to legal work.

President Klaus Iohannis called on Ponta to resign warning Romania could enter a political crisis. He refused and denied wrongdoing.

His coalition government faces a vote of no confidence on Tuesday. A former prosecutor, Ponta has been prime minister since 2012.
