The Democratic Workers Congress is a political party and trade union in Sri Lanka.
The party's origins relate back to the founding of the Ceylon India Congress (CIC) on 25 July 1935, with V. R. M. V. A. Lechumanan Chettiar as its president and Abdul Aziz and H. M. Desai as joint-secretaries.
The Aziz faction subsequently formed the Democratic Workers Congress (DWC) registering the party on 1 January 1956.
In 1968 M. A. Thangavel and A. K. Kandasamy left the DWC and formed the Agricultural Plantation Workers Congress.
The DWC is currently led by Ganeshan's son, Mano, who is a member of parliament, representing the Colombo electorate.
