 The 1952 election was the first contested by the Sri Lanka Freedom Party, which had broken away from the UNP on a platform of Sinhala nationalism, and the Illankai Tamil Arasu Kachchi (Federal Party), which split from the All Ceylon Tamil Congress over joining the UNP government.Because the estate Tamils had been stripped of their citizenship by the Senanayake government, the Ceylon Indian Congress, which most of them had supported, was eliminated from Parliament and the Lanka Sama Samaja Party lost seats.The UNP won a majority, mainly at the cost of the CIC and the LSSP.
