1940 Estonian parliamentary election

According to August Rei, one of independent Estonia's last envoys to Moscow, under the Estonian constitution, the Chamber of Deputies had "no legislative power" apart from the National Council.

[3] The Estonian Working People's Union, a Communist front group, was the only party allowed to run and won all 80 seats, allegedly with 93% of the votes cast and the remaining 7% having been declared invalid.

The newly elected Chamber of Deputies [et] declared the Estonian SSR on 21 July and requested admission to the Soviet Union the following day.

The Communist Party established the Estonian Working People's Union to run in the elections, whilst despite having only three days to organise, the opposition put forward 78 candidates in 66 of the 80 Riigikogu constituencies.

[2] However, Prime Minister Johannes Vares was ordered by Soviet politician Andrei Zhdanov to remove opposition candidates from the ballot.
