JERUSALEM -- A diverse coalition of Israeli opposition parties said Sunday that they have the votes to form a unity government to unseat Israeli Prime Minister Benjamin Netanyahu, Israel's longest-serving leader and its dominant political figure for more than a decade.

Under their agreement, reached after weeks of negotiations spearheaded by centrist opposition leader Yair Lapid, former Netanyahu defense minister and ally Naftali Bennett will lead a power-sharing government.

"We could go to fifth elections, sixth elections, until our home falls upon us, or we could stop the madness and take responsibility," Bennett said in a televised statement Sunday evening. "Today, I would like to announce that I intend to join my friend Yair Lapid in forming a unity government."

Netanyahu has been struggling to hold onto power after four inconclusive elections in the past two years while facing an ongoing corruption trial. Bennett is one of several former loyalists who have flirted with joining the so-called change coalition, a collection of parties that span the political spectrum but share a desire to end Netanyahu's 12-year tenure.
