constitution, which incorporates elements of the 1920 and 1938 Constitutions and explicitly asserts its continuity with the Estonian state as it existed between 1918 and 1940, sees the return of a unicameral parliament with 101 members. The most recent parliamentary elections were held on 3 March 2019. The main differences between the current system and a pure political representation, or proportional representation, system are the established 5% national threshold, and the use of a modified D'Hondt formula (the divisor is raised to the power 0.9). This modification makes for more disproportionality than does the usual form of the formula.
