The motion, signed by 222 lawmakers, was submitted and read out in parliament Sunday.
The Social Democratic Party last week withdrew support for its own prime minister, Sorin Grindeanu, just five months into the Cabinet’s administration, amid a power struggle between Grindeanu and party leader Liviu Dragnea.
For the motion to pass and topple the Grindeanu Cabinet, 233 votes in favor are required. The ruling coalition of the Social Democratic Party and its partner ALDE have a total of 247 lawmakers.
