Israeli Prime Minister Benjamin Netanyahu’s party on Thursday amplified unsubstantiated allegations that Arab-led parties had “stolen” the election, potentially with foreign assistance, as final results showed his bloc had lost its majority in parliament.

The opposition accused Netanyahu of demonizing the Arab population after a historic showing by Arab-led parties in an attempt to delegitimize the election. If the rest of the opposition teams up with Arab parties, a rare and politically risky move, they could potentially form a majority government in parliament, the Knesset.

Results released by election officials early Friday showed Netanyahu’s bloc winning 53 seats in the 120-member assembly, well below the 68 seats it had controlled at its peak in the previous parliament. His main opposition won 48 seats and Arab-led parties secured the other 19.

The count is complete, but the results still need to be certified and submitted to the country’s president next Wednesday.
