The Ceylon Workers' Congress, headed in 1988 by
Suvumyamoorthy Thondaman, originally joined with other Tamil
groups to form TULF, but withdrew from the party after the July
1977 general election, when Jayewardene offered Thondaman a post
in the UNP cabinet. In the late 1980s, the Ceylon Workers'
Congress, with one representative, Thondaman, in Parliament,
continued to cooperate with the ruling party. This was
politically feasible because its principal supporters, Indian
Tamils located for the most part in the central part of the
country, were unresponsive to the Sri Lankan Tamils' call for an
independent state in the north. In December 1986, the Sri Lanka
Muslim Congress, based in the Eastern Province, announced its
determination to become a national political party.
