An ongoing power struggle within Romania's Social Democrat party also saw Tudose's predecessor, Sorin Grindeanu, relinquish his post in June.
Accusations of ballot-rigging and other forms of corruption have dogged the party, which has continued to struggle to gain public confidence.
Street protests in Bucharest and other cities against controversial justice system reforms have occurred alongside public conflicts between politicians and anti-corruption prosecutors, cited by BBC.
Romania is one of the EU's poorest member-nations, but has seen positive financial health over the past two years, projecting an annual economic growth of 5.5 percent in 2018, according to Reuters.
