The First-Past-The-Post (FPTP) system is a type of plurality electoral concept used for direct elections to India's Lok Sabha and State Legislative Assemblies. It is a legacy of British colonialism and the Westminster model of governance. The Constituent Assembly chose to adopt the FPTP system when the Constitution was enacted in 1950, after debating various alternatives, including Proportional Representation (PR). The primary problem it was intended to solve was the need to avoid fragmented legislatures and ensure the formation of stable governments in a newly independent and diverse nation.
The mechanism of FPTP is straightforward: the country is divided into single-member constituencies, and voters cast a vote for a single candidate. The candidate who receives the largest number of votes, or a plurality, is declared the winner, even if they secure less than 50% of the total votes polled. This "winner-takes-all" approach often results in a significant disproportionality between a political party's national vote share and the number of seats it wins in the legislature.
FPTP is closely connected to the alternative electoral systems used in India: the upper house, the Rajya Sabha, and the election of the President are conducted using the Single Transferable Vote (STV), which is a form of Proportional Representation. While the core FPTP system has not been replaced, there is an ongoing debate among political parties and citizens about replacing it with a form of Proportional Representation. Furthermore, the distribution of seats across states is currently based on the population figures from the States Reorganisation Act 1956, as revisions were delayed by a 1976 amendment.
