Following a general election defeat, in June 2015 Helle Thorning-Schmidt, leader of the Social Democrats (''''), resigned as prime minister. She was succeeded by Lars Løkke Rasmussen, the leader of the Liberal Party (''''). Rasmussen became the leader of a cabinet that, unusually, consisted entirely of ministers from his own party. Following the 2019 general election the Social Democrats, led by leader Mette Frederiksen, formed a single-party government with support from the left-wing coalition. Frederiksen became prime minister on 27 June 2019.
