Israel holds a parliamentary election on Tuesday, its first since the Hamas attack on October 7, 2023 that shook the country and plunged the Middle ​East into turmoil.

Prime Minister Benjamin Netanyahu’s hold on power is at stake, with ‌centrist rivals promising to usher in a new era, but it might take time before clear results are known.

WHEN WILL WE KNOW WHO WON?

It is likely this will be known within a few hours of ​polls closing, but it could take days or even weeks to become clear.

Voting starts ​at 7 a.m. (0500 GMT) and ends at 10 p.m. (2000 GMT), when Israeli ⁠TV channels will air exit polls giving the first indications of the outcome. The election ​results will then start coming in.

A clear picture may emerge quickly but if no party ​or group of parties has a clear parliamentary majority, it could take much longer.

The final tally is expected by October 30 and official election results are formally published a week after the election, on November ​4.

WHY IS IT SO COMPLICATED?

Elections to the 120-seat Knesset are meant to be held every ​four years but early elections have been frequent.

The Knesset seats are allocated by proportional representation to national ‌party ⁠lists, with parties needing to pass a threshold of 3.25% of the national vote to secure seats.

About a dozen parties are widely thought to have a chance of crossing the threshold, so the final tally and seat allocation will take time.

WHAT HAPPENS AFTER THE RESULTS ARE PUBLISHED?

After ​the final tally is ​in, President Isaac Herzog ⁠will consult party leaders on whom they want as prime minister and then tap the candidate he believes has the best chance ​of forming a government.

That nominee has up to 42 days to form ​a government.

No ⁠single party in Israel has ever won an outright majority, so governments are formed by a coalition of parties, and negotiations on forming a government often take weeks. Every Knesset seat counts and ⁠small ​parties can have a big impact by becoming kingmakers.

If ​the nominee fails, others can get a chance to try. If no government emerges, another election is called, with ​the present cabinet staying on as a caretaker government.
