Runoff elections are scheduled to be held on Tuesday in municipalities that failed to choose a mayor during nationwide voting two weeks ago.
In each of 38 municipalities, none of the candidates succeeded in obtaining the minimum 40 percent of the vote needed to become mayor.
Ballot boxes are set to open at 1 p.m. and close at 10 p.m.
Although most of the municipalities that ended inconclusively are small, two of the more prominent ones are Herzliya, with a population of over 80,000, and Petah Tikva, which has over 200,000 residents.
Aryeh Deri, the leader of the ultra-Orthodox Shas party, has given his support to Yitzhak Braverman in his battle against incumbent mayor of Petah Tikva, Uri Ahad, the Yedioth Ahronoth newspaper reported Monday. Shas took a beating in the first round of municipal elections when it failed to win the mayor’s seat for its candidates in Jerusalem and the Sephardi-majority town of Elad.
Meanwhile, police continued to investigate accusation of fraud in the town of Beit Shemesh, where ultra-Orthodox mayor Moshe Abutbul retained office by a narrow margin of several hundred votes. Police have questioned several people about the matter and opposition supporters have demanded new elections for the town.
Last week, an associate of the mayor of Beit Shemesh was arrested and remains in police custody over suspicions of involvement in fraud.
Police also questioned eight others, including the son of United Torah Judaism MK Meir Porush, but released them after questioning.
A gag order on the case was lifted late Sunday.
The municipal elections were marked by a low overall voter turnout of 42.6%.
Local governments are elected for five-year terms and have significant influence over major public services, including education, welfare and urban planning.
