Israel's left-wing Labor party, traditionally a staunch opponent of right-wing Prime Minister Benjamin Netanyahu, voted Sunday to join a coalition government he is set to lead.

At a party conference held virtually because of the novel coronavirus pandemic, 64.2 percent of nearly 3,500 voting Labor delegates endorsed the alliance agreed on April 20 between Netanyahu and his centrist election rival Benny Gantz. 

"We are not joining a right-wing government," Labor leader Amir Peretz said in a statement. 

"We are joining an egalitarian unity government with power-sharing."

Labor had backed Gantz's efforts to form a government following Israel's three inconclusive elections over the past year. But the former army chief was unable to forge a viable governing coalition, given the deep divisions within the anti-Netanyahu bloc. 

Netanyahu and Gantz signed a three-year coalition agreement on April 20 that ends the political stalemate and sees the job of prime minister rotating between the two men. 

Netanyahu will serve as premier for 18 months, with Gantz as his alternate. They will switch roles midway through the deal.

Labor, Israel's founding political party, which has repeatedly led the country since its creation in 1948, has seen its political fortunes wither.

It only earned three out of 120 parliamentary seats in the country's March 2 vote.

In joining the prospective coalition, Peretz is expected to be named economy minister, while another party official is likely to be named social affairs minister.
