Elections to the seventh Supreme Soviet were held in the Soviet Union on 12 June 1966.^[1]

Electoral system

Candidates had to be nominated by the Communist Party of the Soviet Union (CPSU) or by a public organisation.^[2] However, all public organisations were controlled by the party and were subservient to a 1931 law that required them to accept party rule.^[2] The CPSU itself remained the only legal one in the country.^[3]

Voters could vote against the CPSU candidate if they wished, but could only do so by using polling booths, whereas votes for the party could be cast simply by submitting a blank ballot.^[2] Turnout was required to be over 50% for the election to be valid.^[2]

Candidates

CPSU candidates accounted for around three quarters of the nominees, whilst many of the others were members of Komsomol.^[4]
