Core Event: Statement and Meeting
On April 29 2026, New York City Mayor Zohran Mamdani told reporters that, if given a private moment with King Charles III, he would “encourage him to return the Koh-i-Noor diamond.” Later that day the mayor stood beside the monarch at a wreath-laying ceremony at the 9/11 Memorial, where the two briefly shook hands. Neither Mamdani’s office nor Buckingham Palace confirmed whether the diamond issue was raised during the encounter.
Historical Background of the Koh-i-Noor
The Koh-i-Noor is a 105-106-carat diamond originally mined in the Golconda region of South India. In 1849, after the British annexation of Punjab, the East India Company forced the ten-year-old Sikh ruler Duleep Singh to sign the Treaty of Lahore, surrendering the stone to Queen Victoria. It was displayed at the 1851 Great Exhibition, later recut to an oval brilliant, and set in the Crown of Queen Elizabeth the Queen Mother, now displayed in the Tower of London. India, Pakistan, Iran and Afghanistan have all claimed ownership.
Key Figures
- Zohran Mamdani – New York City mayor, first democratic-socialist mayor, of Indian-Ugandan heritage.
- King Charles III – British monarch on a four-day state visit to the United States.
- Buckingham Palace – Official residence of the British royal family, which declined comment on Mamdani’s remarks.

Data & Statistics

Official Statements & Responses
Mamdani framed his comment as a private suggestion, emphasizing that his primary focus was the 9/11 remembrance. Buckingham Palace issued a brief statement declining to comment on the mayor’s remarks. Indian officials reiterated that the diamond was taken during colonial rule and should be returned, describing it as a “symbol of imperial exploitation.” The Historic Royal Palaces charity confirmed the stone’s provenance and current setting.
Criticism & Opposition
Reform UK’s home-affairs spokesman Zia Yusuf dismissed the mayor’s demand, asserting the diamond “will stay” at the Tower of London. Academic Danielle Kinsey argued that retaining looted artifacts like the Koh-i-Noor is a public-relations liability for the monarchy and that restitution is the “right thing to do.”
Conflicting Reports & Gaps
Sources differ on whether Mamdani actually raised the issue with King Charles during their brief interaction; no transcript exists, and both the mayor’s office and Buckingham Palace declined to confirm. Media outlets reported the meeting as “all smiles,” but the substantive content remains unknown.
Why It Matters
The episode spotlights ongoing debates over colonial restitution, the symbolic power of crown jewels, and the diplomatic sensitivities of a high-profile royal visit to the United States. Mamdani’s public call may influence future UK-India cultural negotiations and adds a contemporary political dimension to the historic controversy.
