General elections were held in San Marino on 20 November 2016 and 4 December 2016.[1] The San Marino First alliance received a plurality of the popular vote, but fell short of a majority in the Grand and General Council, initially being allocated 25 seats.[2] As no single bloc had won a majority of seats, a runoff was held on 4 December 2016 between the top two coalitions, San Marino First and Adesso.sm, to determine the winner of the majority prize.[3] The second round saw Adesso.sm win with 58% of the vote, resulting in seats being reallocated and the winning alliance receiving 35 seats.[4]
See main article: Elections in San Marino.
The 60 members of the Grand and General Council were elected by party-list proportional representation, with seats allocated using the d'Hondt method. The electoral threshold is calculated by multiplying the number of parties running in the elections by 0.4, with a maximum possible threshold of 3.5%.[5]
If no single bloc obtained an absolute majority, a runoff election would be held between the two most popular coalitions, of which the winner will obtain a majority jackpot – a seat bonus ensuring a majority.[6]
