Ceylon National Congress which was founded by
Sir Ponnambalam Arunachalam and
Sir James Peiris in 1919. He was elected to the
State Council of Ceylon in 1931 from Kegalle, where he served until 7 December 1935. He did not stand for re-election at the State Council in 1936 and return to his legal practice. On 21 December 1940, Wijeyeratne was appointed President of the Ceylon National Congress. His Joint Secretaries were
Dudley Senanayake and
JR Jayawardene. During this period he was chosen to lead the Ceylon National Congress delegation to London. A famous story at the time was in 1944 when the
Soulbury Commission was on their way to
Kandy, D. S. Senanayake had stationed Wijeyeratne bare-bodied, in a paddy field in Kegalle. There, he was introduced to the commissioners as a typical Sinhala farmer and who spoke in English to the commissioners and impressed on them the need for Ceylon to obtain self-government. A special invitation was thereby sent to Ceylon by
Jawaharlal Nehru and the Indian Congress to visit India for a discussion regarding the independence of Ceylon. Wijeyeratne, D. S Senanayake, George E. De Silva,
J. R. Jayawardene,
Sir Claude Corea and
H. W. Amarasuriya were among the delegates.
