The chairman of the Social Democratic Party, Liviu Dragnea, yesterday said Grindeanu, in office since January, failed to implement the party's governing program.
Grindeanu said he'll resign only after President Klaus Iohannis nominates a replacement from his party. Iohannis, a rival of the Social Democrats, said through his spokeswoman yesterday he'll only start the process once Grindeanu quits or loses a confidence vote.
The Social Democrats and a junior partner will submit a vote of no-confidence on Monday and it will be voted on later in the week.
The Social Democrats also voted yesterday to expel Grindeanu from the party.
The premier claimed the dispute is politically motivated. "The only answer I could find is the wish of a certain man to have all the power," he said in reference to Dragnea.
