Israeli political parties were making a concerted effort Monday to woo undecided voters as the campaign entered its final 24 hours, dpa reported.
Voting begins at 0500 GMT Tuesday, and the last polls allowed to be published on Friday showed that around 20 per cent of the electorate had yet to make up its mind for whom to cast a ballot.
According to the surveys, the result of the election is not in doubt - Prime Minister Benjamin Netanyahu will continue in office - but the strengths of the parties can have an effect on coalition negotiations and on their influence in parliament.
The Ynet news site reported that candidates and party activists were taking to the streets, the telephones, and the internet in last-ditch persuasion efforts.
Netanyahu's Likud-Beteinu faction, which is predicted to emerge as the strongest faction with around 35 of the 120 seats at stake, far fewer then originally predicted, was trying to convince voters that a large ruling party was essential for stable governance.
The centre-left Labour Party leader Shelly Yachimovich intended to travel in a special bus soliciting votes, while former television anchorman Yair Lapid was to telephone wavering voters to ask them to support his centre-left party Yesh Atid.
Naftali Bennett, leader of the ultra-nationalist Jewish Home Party, which has been touted as the surprise of the election and is expected to quadruple its current representation of three seats, will make an effort to target young voters and those from the former Soviet Union.
On Monday night, Bennett will spend time in a pub in Tel Aviv, chatting with potential voters, Ynet reported.
Voting ends at 2000 GMT Tuesday, when Israel's three television channels will broadcast exit polls.
