In order to achieve equality in Israel, every citizen must perform either military or civilian national service, whether they are Jewish or Arab, religious or secular, former Kadima chairwoman Tzipi Livni on Sunday.

Livni was speaking to members of "Camp Sucker," a movement calling for equal service from all segments of the Israeli population, at their tent encampment in Tel Aviv.

She said that if some segments of Israeli society opt out of serving the country, there should be a limit to the number that are allowed to do so, adding that Israel cannot talk about morals, equality and democracy when only some of its population serves.

"Those who do not follow the law must have sanctions levied against them," she said.

Livni declined to answer questions on whether Kadima should leave Prime Minister Binyamin Netanyahu's coalition. Kadima MKs loyal to her have spoken openly about using the dispute over drafting yeshiva students to split the party.
