Sofia Municipality is identical to Sofia City Province, which is distinct from Sofia Province, which surrounds but does not include the capital itself. Besides the city proper, the 24 districts of Sofia Municipality encompass three other towns and 34 villages. Districts and settlements have their own governor who is elected in a popular election. The assembly members are chosen every four years. The common head of Sofia Municipality and all the 38 settlements is the mayor of Sofia. The mayor Yordanka Fandakova is serving a third consecutive term, having won the 2015 election at first round with 238,500 votes, or 60.2% of the vote, when Reformist Bloc opponent Vili Lilkov was second with 9.6%; the turnout was 41.25%. Some party leaders claimed that ballots were falsified and called for annulment of the election. A precedent happened, due to the suspicion, as a preventative action between 300 and 5000 people and counters had been locked inside Arena Armeets against their will for two days, following which the director of the Electoral Commission of Sofia resigned at the request of Prime Minister Boyko Borisov.
