New York Mayor Calls for Return of Koh-i-Noor Diamond Ahead of Meeting with King Charles at 9/11 Memorial
During King Charles III and Queen Camilla’s visit to the 9/11 Memorial in New York on April 29, 2026, Mayor Zohran Mamdani stated he would encourage the monarch to return the Koh-i-Noor diamond if they spoke privately. The 105-carat gem, acquired by the British in 1849 from a 10-year-old Indian ruler, has been the subject of longstanding repatriation demands from India. Mamdani and Charles briefly met and shook hands at the public ceremony, but it is unclear if the diamond was discussed. Buckingham Palace declined to comment. The incident drew political reactions, including criticism from Reform UK’s Zia Yusuf, who threatened to ban Mamdani from Britain. The diamond remains part of the British Crown Jewels, set in the crown of Queen Elizabeth the Queen Mother.
The sources collectively highlight a single event—the interaction between King Charles and Mayor Mamdani—but frame it through distinct ideological, historical, and political lenses. While all agree on core facts, their emphasis varies from royal symbolism (The Guardian) to anti-colonial critique (BBC News) to culture-war provocation (Daily Mail). The most complete and balanced accounts are BBC News and TheJournal.ie, while Daily Mail is the most ideologically charged.
