Israel could be looking at the imminent end of Prime Minister Benjamin Netanyahu's record run as the country's leader, The BBC reported Monday.
Naftali Bennett, the ultra-nationalist leader said his party would engage in talks to create a governing alliance with Israeli opposition leader Yair Lapid to unseat the prime minister.
Netanyahu, who is on trial for fraud, bribery and breach of trust charges, which he denies, couldn't muster enough votes at a general election in March.
It was Israel's fourth inconclusive vote in two years which saw Netanyahu falling short, again, of securing coalition allies.
Lapid, 57, is seeking a diverse coalition Israeli journalists have dubbed a federation for "change", which would include Arab-Israeli lawmakers.
According to media reports, Lapid was close to putting together an alliance that would end Netanyahu's 12-year rule as Israeli leader.
With pressing issues like how to keep the ceasefire holding with Hamas-led militants in Gaza and escalating tensions in the West Bank and East Jerusalem, this could be a fragile government easily torn apart by ideological divisions, CNN said.
A former defense minister, the 49-year old Bennett has changed course before over ousting Netanyahu, a right-wing leader in power consecutively since 2009.
Bennett and Lapid's parties began talks Sunday night to formalise the agreement, they said in a statement.
"God willing, together we can save the country from a tailspin and return Israel to its course," part of the statement read, according to The Associated Press.
Netanyahu, in his own televised address shortly after lashed out at the plan, calling it "a danger for the security of Israel" and accused Bennett of orchestrating the "fraud of the century."
Before the announcement, Israeli media reported that under the proposed conditions of the deal, Bennett would replace Netanyahu as prime minister and later give way to Lapid.
The arrangement has not been officially confirmed, The BBC said.
