15 June 1977, two ballots
On 15 June 1977, Spaniards voted nationwide for all 350 deputies and 207 elected senators of a new bicameral Cortes. It was the country's first national election since February 1936 contested by a broad range of parties.
Citizens aged 21 or older chose the Congress by proportional representation and the Senate by a limited-vote majority system, generally selecting no more than three candidates. Of 23,583,762 registered voters, 18,590,130 voted — a turnout of 78.83 percent.
A plurality, eleven seats short
Adolfo Suárez's Union of the Democratic Centre took 165 Congress seats. An absolute majority required 176.
The PSOE electoral family, led nationally by Felipe González, won 118 seats: 103 under the PSOE candidacy and 15 under the allied Catalan Socialist label.
What the election was, legally
The vote had been scheduled by Royal Decree 679/1977, under a Political Reform Law that created an elected bicameral legislature. The chambers were elected as an ordinary Cortes; the decree did not explicitly mandate a constituent assembly.
They became constituent in substance, and are conventionally called the Constituent Cortes: these were the chambers that drafted the Constitution ratified by referendum on 6 December 1978.

What the sources leave uncertain
- The assembly was formally elected as an ordinary bicameral Cortes under the existing reform law. It became constituent in substance and is conventionally called the Constituent Cortes, but the election decree did not explicitly mandate a constituent assembly.
- Contemporary and later datasets differ slightly in some vote totals and turnout calculations. The figures here use the Spanish Interior Ministry's retrospective national series for turnout and Congress/Junta Electoral Central figures for seats.
