Prime Minister S.W.R.D. Bandaranaike (left) and S.J.V. Chelvanayagam, leader of the Thamil Arasu Katchi, shake hands after signing what came to be known as the Bandaranaike-Chelvanayagam Pact on July 26, 1957. Bandaranaike repudiated the agreement in April 1958 in view of a campaign led by the Buddhist clergy and sections of the Sinhala political leadership, including Jayewardene, who was then Leader of the Opposition.
