Pedro Sánchez Pérez-Castejón (born 29 February 1972) is a Spanish politician who has served as Prime Minister of Spain since 2018. He has also been Secretary-General of the PSOE since 2017, having previously held that office from 2014 to 2016, and was elected President of the Socialist International in 2022.
Sánchez began his political career in 2004 as a city councillor in Madrid, before being elected to the Congress of Deputies in 2009. In 2014, he was elected Secretary-General of the PSOE, becoming Leader of the Opposition. He led the party through the inconclusive 2015 and 2016 general elections, but resigned as Secretary-General shortly after the latter, following public disagreements with the party's executive. He was re-elected in a leadership election eight months later, defeating internal rivals Susana Díaz and Patxi López.
