Having lost his seat in parliament, Jayewardene pushed the party to accommodate nationalism and endorse the Sinhala Only Act, which was bitterly opposed by the island's minorities. When Bandaranaike came to an agreement with S.J.V. Chelvanayagam in 1957, to solve the outstanding problems of the minorities, Jayawardene led a "March on Kandy" against it, but was stopped at Imbulgoda S. D. Bandaranayake. The U.N.P.'s official organ the "Siyarata" subsequently ran several anti-Tamil articles, including a poem,containing an exhortation to kill Tamils in almost every line.
