Francisco Manuel Lumbrales de Sá Carneiro, GCTE, GCC, GCL (Portuguese: [fɾɐ̃ˈsiʃku sa kɐɾˈnɐjɾu] (listen); 19 July 1934 – 4 December 1980) was a Portuguese politician, Prime Minister of Portugal for most of 1980, and founder of the Social Democratic Party. He only held office of Prime Minister for eleven months, dying in a plane crash with his partner, "Snu" Abecassis (born Ebba Merethe Seidenfaden), on 4 December 1980.
