A Likud victory in next week’s elections is not guaranteed, Prime Minister Binyamin Netanyahu warned on Tuesday evening, as polls showed the joint Labor-Hatnua list opening its largest lead over the Likud.

“In one week we’ll find out if the attempt to bring down the Likud government failed. I want to tell you tonight that this attempt must not succeed: we need to ensure that the Likud will form the next government,” Netanyahu wrote on his Facebook page.

“A Likud victory is far from certain. People who are considering voting for another party in the nationalist camp must have this explained to them – you should know that there is a real possibility that if this gap between the Likud and the Labor party will grow, we may wake up in a week and find Tzipi [Livni] and Buji [Herzog] as Prime Ministers of Israel,” he warned.

“Those who do not want this to happen must talk to others and tell them honestly: Go vote Likud so that we can continue to protect the state of Israel, Israel’s security, the lives of our children.

“We need one big Likud – you cannot divide the votes among the parties. Any vote that goes against the Likud will increase the gap with the left which means that the task of forming the government will be imposed on them and not on us,” wrote Netanyahu.

A Channel 2 poll on Tuesday evening gave Labor 25 seats, while Likud flounders at 21. The findings widen the divide from an earlier poll on Tuesday, which gave Labor 24 versus 21 to Likud.

Meanwhile, a poll conducted for Army Radio on Tuesday morning found that 16% of eligible voters are still undecided, amounting to some 19 seats which are enough to be a deal-breaker in the race between right and left. 

Overall, the margin of “undecided” voters is still narrowing, however, as some 21% of voters were still on the fence about their choice two weeks ago.
