Netanyahu told by Israel’s supreme court he must fire key ally from cabinet

Prime minister's coalition in jeopardy after Aryeh Deri ruled ineligible for government due to tax offences

Israel's supreme court has ruled that the prime minister, Benjamin Netanyahu, must fire a key ally from the country's new cabinet, presenting the Israeli leader with a potential coalition crisis and deepening a rift over the power of the courts.

Ten of 11 judges on the high court found that Aryeh Deri, the influential head of the ultra-Orthodox Shas party who has served repeatedly in Netanyahu's previous governments, is disqualified from serving as a minister after he was convicted last year for tax offences and placed on probation as part of a plea deal. Deri has pledged not to quit and met Netanyahu after the ruling.
