UN Rights Monitors Challenge UAE Diplomat Lana Nusseibeh's Bid for Secretary-General

Just hours before United Arab Emirates diplomat Lana Nusseibeh was scheduled to defend her candidacy for United Nations secretary-general, human rights experts launched a coordinated campaign to disqualify her. The 48-year-old former ambassador entered the deadlocked race in late October 2026, seeking to succeed António Guterres.[2][5]

The opposition centers on Nusseibeh’s consistent defense of the UAE against allegations that it is fueling the devastating civil war in Sudan. Rights groups argue that her repeated denials of Emirati military support for the paramilitary Rapid Support Forces make her unfit to lead the world’s top diplomatic body.[1][3]

"We cannot afford to have the UN led by somebody who is a genocide denier," Kenneth Roth, the former executive director of Human Rights Watch, said during a virtual media briefing on October 27. Roth accused Nusseibeh of shielding Abu Dhabi from accountability while the RSF commits widespread atrocities.[2][3][5]

The conflict in Sudan, which erupted in April 2023 between the Sudanese Armed Forces and the RSF, has displaced more than 14 million people. The United Nations Fact-Finding Mission on Sudan recently concluded that the RSF's assault on the North Darfur capital of El Fasher bore the hallmarks of genocide.[1][5]

Rejecting UN findings

Nusseibeh has spent years categorically rejecting accusations that the UAE is arming the RSF. In an April 2024 letter to the UN Security Council, she dismissed allegations of military, logistical, or financial support for any Sudanese faction as spurious and unfounded.[1][2]

Those denials directly contradict the findings of the UN's own investigative bodies. A recent UN panel of experts report found credible allegations that the Emirati government has provided weapons and instrumental support to the RSF through supply lines in neighboring Chad.[1][2]

"Having dismissed and undermined the findings of the UN’s own reports, UN member states should be asking tough questions about Nusseibeh’s willingness to defend the independence and integrity of the UN," said Bruno Stagno Ugarte, chief advocacy officer at Human Rights Watch.[1]

Sudanese diplomats and civil society leaders have echoed these concerns, warning that electing the UAE's senior diplomat would place the UN in the hands of the government's chief defender. Husam Mahjoub, founder of Sudan Bukra TV, argued this would happen just when Sudanese civilians desperately need powerful states held to account.[2][5]

During a dialogue with the General Assembly on Tuesday, Nusseibeh faced direct questions about this perceived conflict of interest. Yonah Diamond, legal adviser at the Raoul Wallenberg Center for Human Rights, asked how she could assure the international community that she would not continue to reject the findings of the organization she seeks to lead.[2]

A deadlocked succession race

Replying to the allegations, Nusseibeh pledged that Sudan would be her absolute priority as secretary-general. "The loss of human life on the ground is a tragedy, the atrocities committed by the RSF are atrocious, and I would support the work of all UN fact-finding missions for accountability and transitional justice," she told the assembly.[2][5]

Nusseibeh also promised to defend human rights without double standards and to protect the independence of the secretary-general’s office. She emphasized that the UN chief takes instruction from no government and answers only to the UN Charter, pledging to be a risk-taker in mediation efforts.[2][5]

The Emirati diplomat's late entry into the race comes as the UN Security Council struggles to find a consensus successor to Guterres, whose second term ends on December 31, 2026. After six informal straw polls, no candidate has secured the required backing without facing a veto from one of the five permanent members.[2][4][5]

An informal council poll earlier in October placed former Costa Rican Vice President Rebeca Grynspan narrowly ahead. However, Grynspan and every other declared candidate drew at least two opposing votes from the permanent members—the United States, Britain, France, Russia, and China.[2][5]

Nusseibeh brings a formidable diplomatic resume to the contest, having served as the UAE's permanent representative to the UN from 2013 to 2024. Diplomats in New York widely describe her as a highly capable manager, a skilled negotiator, and a clear communicator who successfully led the UAE's recent Security Council tenure.[2][5]

Geopolitical backing and backlash

If selected, Nusseibeh would become the first woman and only the second Arab to lead the United Nations. She has already secured the unanimous backing of the six Gulf Cooperation Council states, and diplomatic sources indicate that Britain is leaning toward supporting her nomination.[3][4]

Her candidacy also carries unique geopolitical weight due to her Palestinian heritage and her family's roots in Jerusalem. Nusseibeh has been a vocal advocate for humanitarian aid to Gaza, while simultaneously defending the UAE's historic 2020 Abraham Accords normalization agreement with Israel.[3][4]

Yet that same regional positioning has drawn additional scrutiny from critics. Former UN human rights official Craig Mokhiber accused Nusseibeh of promoting the normalization of the Israeli government while it conducts a devastating military campaign in Gaza, calling her a truly terrible candidate.[3][4]

The campaign against Nusseibeh has rapidly gained traction, with advocacy groups organizing a coalition that has generated tens of thousands of emails to UN embassies. The opposition includes Sudanese survivors, international legal experts, and prominent non-governmental organizations.[2][5]

For the Sudanese diplomats opposing her bid, the stakes extend beyond the UN's leadership crisis to the survival of their nation. Sudan's permanent mission to the UN stated that the UAE must face accountability for its actions, rather than being rewarded with the top global leadership role.[3]

As the Security Council prepares for its next straw poll, the controversy surrounding Nusseibeh highlights a broader crisis of trust within the UN. Member states must now weigh her diplomatic capabilities against the severe reputational risks of elevating a candidate so deeply entangled in one of the world's most horrific ongoing conflicts.[2][4]
