JERUSALEM — Firebrand Arab MP Haneen Zuabi, a regular critic of Israel’s right-wing government, was banned Thursday from standing in next month’s general election.

The elections committee gave no reason for the disqualification, reported on its website, but Zuabi’s lawyer Hassan Jabareen said it was because she was deemed “hostile to the Jewish state”.

A member of the leftwing Arab-Israeli Balad party, the 45-year-old Zuabi was also banned ahead of the 2013 election in a move overturned by the Supreme Court.

The country’s top tribunal must also rule in this case.

Zuabi rejects the concept of Israel as a Jewish state and of it living alongside an independent Palestinian state. Instead, she supports the idea of a single state in which Jews and Arabs have equal rights.

Israel has 1.3 million Arab citizens, about 20 percent of the population. They are the descendants of 160,000 Palestinians who remained on their land when the state of Israel was established in 1948.

Zuabi’s opponents also claim she backed enemies of the state by participating in a 2010 bid to break Israel’s maritime blockade of the Gaza Strip. An Israeli commando raid on the Mavi Marmara flotilla killed nine Turkish activists.

The latest action against her was brought by members of the governing right-wing Likud party and the ultra-nationalist Yisrael Beitenu party on the grounds that she supports the “armed struggle against Israel.”
