Jóhanna Sigurðardóttir (born 4 October 1942), is the Prime Minister of Iceland. Many years a politician, she was previously Iceland's Minister of Social Affairs and Social Security from 1987–1994 and 2007–2009. She has been a member of the Althing (Iceland's parliament) for Reykjavík constituencies since 1978, winning re-election on eight successive occasions. She became Iceland's first female Prime Minister and the world's first openly lesbian head of government on 1 February 2009.
Jóhanna is a social democrat and Iceland's longest-serving member of Parliament. In the 1990s, when she lost a bid to head the party, she lifted her fist and declared "Minn tími mun koma!" ("My time will come!"), a phrase that became a popular Icelandic expression. In 2009, Forbes listed her among the 100 Most Powerful Women in the world.
Jóhanna married Þorvaldur Steinar Jóhannesson in 1970 and the couple had two sons (born 1972 and 1977).
After their divorce, she joined in a civil union with Jónína Leósdóttir (born 1954), an author and playwright, in 2002. In 2010, when same-sex marriage was legalised in Iceland, Jóhanna and Jónína changed their civil union into a marriage, thus becoming one of the first same-sex married couples in Iceland.
