Party of the Democratic Left (Slovakia)

The Party of the Democratic Left (Slovak: Strana demokratickej ľavice, SDĽ) was a social-democratic political party in Slovakia from 1990 to 2004. It was founded in 1990 out of the Communist Party of Slovakia.

From 1994 to 1997, SDĽ was a member of a coalition called "Common Choice" (Spoločná voľba) that gained 10.18% (18 seats) in the Slovak parliament. They did not form a part of the government.

Since the 2002 elections, it has had no place in the Slovak legislature. It was a member of the Party of European Socialists and the Socialist International.

On 4 December 2004, the party membership voted to merge with Direction – Social Democracy from 1 January 2005. The latter party had broken off from the SDL five years earlier.
