 The Marxist Lanka Sama Samaja Party (LSSP), which grew out of the Youth Leagues in 1935, made the demand for outright independence a cornerstone of their policy.Its deputies in the State Council, N.M. Perera and Philip Gunawardena, were aided in this struggle by Colvin R. De Silva, Leslie Goonewardene, Vivienne Goonewardene, Edmund Samarkody and K. Natesa Iyer.They also demanded the replacement of English as the official language by Sinhala and Tamil.
