rapporteur on human rights in Myanmar, criticised Aung San Suu Kyi's response to the "really grave" situation in Rakhine, saying: "The de facto leader needs to step in—that is what we would expect from any government, to protect everybody within their own jurisdiction." The BBC reported that "Her comments came as the number of Rohingya fleeing to Bangladesh reached 87,000, according to UN estimates", adding that "her sentiments were echoed by Nobel Peace laureate Malala Yousafzai, who said she was waiting to hear from Ms Suu Kyi—who has not commented on the crisis since it erupted". The next day George Monbiot, writing in The Guardian, called on readers to sign a change.org petition to have the Nobel peace prize revoked, criticising her silence on the matter and asserting "whether out of prejudice or out of fear, she denies to others the freedoms she rightly claimed for herself. Her regime excludes—and in some cases seeks to silence—the very activists who helped to ensure her own rights were recognised." The Nobel Foundation replied that there existed no provision for revoking a Nobel Prize. Archbishop Desmond Tutu, a fellow peace prize holder, also criticised Aung San Suu Kyi's silence: in an open letter published on social media, he said: "If the political price of your ascension to the highest office in Myanmar is your silence, the price is surely too steep ... It is incongruous for a symbol of righteousness to lead such a country." On 13 September it was revealed that Aung San Suu Kyi would not be attending a UN General Assembly debate being held the following week to discuss the humanitarian crisis, with a Myanmar government spokesman stating "perhaps she has more pressing matters to deal with". In October 2017, Oxford City Council announced that, following a unanimous cross-party vote, the honour of Freedom of the City, granted in 1997 in recognition of her "long struggle for democracy", was to be withdrawn following evidence emerging from the United Nations which meant that she was "no longer worthy of the honour". A few days later, Munsur Ali, a councillor for City of London Corporation, tabled a motion to rescind the Freedom of the City of London: the motion was supported by Catherine McGuinness, chair of the corporation's policy and resources committee, who expressed "distress ... at the situation in Burma and the atrocities committed by the Burmese military".
