Pedro Sánchez Pérez-Castejón (Spanish: , born 29 February 1972) is a Spanish economist and politician serving as Prime Minister of Spain since 2 June 2018. He is also Secretary-General of the Spanish Socialist Workers' Party (PSOE), holding office for the second time after winning a leadership election in June 2017.
He served as town councillor in the City Council of Madrid from 2004 to 2009. In 2009, he was first elected Deputy in the Congress. In 2014, he became Secretary-General of the PSOE, and he was the party's candidate for prime minister in the 2015 and 2016 general elections. During his first term as Secretary-General, he was heavily opposed to the re-election of Rajoy as Prime Minister. Rajoy needed the abstention of the PSOE in the Congress of Deputies in order to secure a parliamentary majority. Tensions grew within the party that allowed Rajoy to form a government; due to its opposition by Sánchez, he stepped down as Secretary-General on 1 October 2016. He simultaneously resigned as Deputy, and a caretaker committee took over the PSOE leadership. He would eventually win the party primaries, defeating Susana Díaz and Patxi López, and was reinstated Secretary-General in June 2017. Under his tenure, the party backed the Government of Spain in its handling of the Catalan independence referendum and the subsequent constitutional crisis.
