**United Russia kept its Duma majority while the Communist Party remained second, and Turnout fell to Just over half of voters.**

United Russia retained a solid majority in the state Duma after the September 30 vote. The Communist Party of the Russian Federation finished in second place, while the Liberal Democratic Party of Russia took third. Turnout was recorded between 53 and 56 percent of eligible voters.

United Russia secured between 325 and 339 seats in the New Duma. This tally did not exceed the party's 2021 seat count. The result also confirmed that United Russia gained more seats than any other party in the election.

The Communist Party of the Russian Federation placed second but did not increase its seat total from the 2021 election. Its share of seats remained unchanged, preserving its role as the principal opposition bloc. The party's performance reflected a stable, though not expanding, Parliamentary presence.

The Liberal Democratic Party of Russia finished in third place. It remained behind both United Russia and the Communist Party in the seat distribution. The party's position reaffirmed its status as the third-largest force in the legislature.

Voter Turnout was recorded between 53 and 56 percent, a slip to Just over half of the electorate. This represented a decline from previous Parliamentary elections.

## Analysis

United Russia's ability to keep a solid majority, combined with President Vladimir Putin remaining in office, means that the current policy trajectory is likely to continue without major legislative disruption. The party also captured the most seats, reinforcing its dominant position within the Duma.

The seat range of 325 to 339, together with the fact that United Russia did not increase its seat count from 2021, suggests that the party's support may have plateaued. The modest seat total despite a strong majority indicates limited growth potential, possibly constrained by the reduced voter Turnout

The Communist Party's second-place finish, without any gain in seats, limits its capacity to challenge United Russia's agenda. While it remains the main opposition force, the static seat count signals that it has not expanded its Parliamentary influence since the last election.

Turnout falling to between 53 and 56 percent points to a decline in electoral participation. A lower Turnout can affect the perceived legitimacy of the Duma and may influence how parties strategize for future elections, especially if voter disengagement continues.
