Israel on Tuesday called for a UN inquiry into its 50-day war in Gaza last summer to be shelved as its chairman quit over Israeli accusations of conflict of interest. Canadian international law expert William Schabas tendered his resignation on Monday after Israel complained that he had prepared a legal opinion for the Palestine liberation Organisation in October 2012, the United Nations said. Prime Minister Benjamin Netanyahu welcomed the departure of a man he said was “biased against Israel”, but said the whole investigation needed to be abandoned as it had been commissioned by the UNHRC, which he described as an “anti-Israel body”.
