Kulanu became the latest party to back Netanyahu as the next Prime Minister during consultations with the country's President Reuven Rivlin.
"The parties, which are represented in the Knesset with 67 legislators, have supported the nomination of Benjamin Netanyahu for Prime Minister," Presidential adviser Jason Pearlman told RIA Novosti on Monday.
Four other, smaller parties also gave their backing to Netanyahu, who is expected to be officially appointed by the President on Wednesday.
The biggest opposition party, the Zionist Union, recommended their leader Isaac Herzog, but the 24 seats the party had won in the election were not enough.
The Joint List and Yesh Atid, two other opposition parties in the Knesset, did not nominate a candidate.
