The Labour Federation (Italian: Federazione Laburista, FL) was a social-democratic political party in Italy.
The FL was founded by members of the Italian Socialist Party (PSI) in November 1994, a few days before the PSI's dissolution, and entered into a close alliance with the Democratic Party of the Left (PDS).
In February 1998 the FL was merged with the PDS and some minor parties from the centre-left coalition (the Social Christians, Republican Left, etc.)
In 1998, after the merger into the DS, the FL evolved as an internal faction within the party and was renamed Labourites – Liberal Socialists (LS).
Those who decided to join the PD took part in To the Left, which the LS faction finally merged into in July 2008.
