The potential appointment of Penny Green or Michael Lynk as the United Nations' Special Rapporteur on the Palestinian territories has prompted outrage around the world.
British lawyers have written to Foreign Office minister Baroness Anelay opposing both candidates, while members of the Canadian Conservative Party have sent a letter to Prime Minister Justin Trudeau, urging him to speak out against the move.
Non-governmental organisation UN Watch has also published a damning report outlining the pair's strongly anti-Israel background.
Ms Green, a professor of law and globalisation at Queen Mary University of London, was chosen by the UN Human Rights Council's Consultative Group as the top candidate for the position.
