to that of the Sinhalese (65% of the population). This "50-50" or "balanced representation" policy became the hall mark of Tamil politics of the time. Ponnambalam also accused the British of having established colonization in "traditional Tamil areas", and having favoured the Buddhists by the Buddhist temporalities act. The Soulbury Commission rejected the submissions by Ponnambalam and even criticized what they described as their unacceptable communal character. Sinhalese writers pointed to the large immigration of Tamils to the southern urban centres, especially after the opening of the Jaffna-Colombo railway. Meanwhile, Senanayake, Baron Jayatilleke, Oliver Gunatilleke and others lobbied the Soulbury Commission without confronting them officially. The unofficial submissions contained what was to later become the draft constitution of 1944. The close collaboration of the D. S. Senanayake government with the war-time British administration led to the support of Lord Louis Mountbatten. His dispatches and a telegram to the Colonial office supporting Independence for Ceylon have been cited by historians as having helped the Senanayake government to secure the independence of Sri Lanka. The shrewd cooperation with the British as well as diverting the needs of the war market to Ceylonese markets as a supply point, managed by Oliver Goonatilleke, also led to a very favourable fiscal situation for the newly independent government. The Second World War Sri Lanka was a front-line British base against the Japanese during World War II. Sri Lankan opposition to the war led by the Marxist organizations and the leaders of the LSSP pro-independence group were arrested by the Colonial authorities. On 5 April 1942, the Indian Ocean raid saw the Japanese Navy bomb Colombo. The Japanese attack led to the flight of Indian merchants, dominant in the Colombo commercial sector, which removed a major political problem facing the Senanayake government. Marxist leaders also escaped to India where they participated in the independence struggle there. The movement in Ceylon was minuscule, limited to the English-educated intelligentsia and trade unions, mainly in the urban centres. These groups were led by Robert Gunawardena, Philip's brother. In stark contrast to this "heroic" but ineffective approach to the war, the Senanayake government took advantage to further its rapport with the commanding elite. Ceylon became crucial to the British Empire in the war, with Lord Louis Mountbatten using Colombo as his headquarters for the Eastern Theatre. Oliver Goonatilleka successfully exploited the markets for the country's rubber and other agricultural products to
