Mihai Tudose is a Romanian politician, deputy in the Parliament of Romania, a former Minister of Economy in 2017 and a former Prime Minister of Romania in 2018. On 16 January, 2018 he resigned from his position as Prime Minister after his own Social Democratic Party (PSD) retracted its political support for his government. He subsequently switched from PSD to Victor Ponta's party PRO Romania in 2019.

The Social Democratic Party is the largest social democratic political party in Romania and also the largest overall political party in the country, aside from European Parliament level, where it is the second largest by total number of political representatives, after the National Liberal Party (PNL). It was founded by Ion Iliescu, Romania's first democratically elected president at the 1990 Romanian general election. It is currently part of the National Coalition for Romania (CNR), which is a big tent grand coalition comprising also the National Liberal Party (PNL). The CNR formerly included the Democratic Alliance of Hungarians in Romania (UDMR/RMDSZ) until mid June 2023.
