I love how people argue over pedantic details that a 10 second Wikipeida search can resolve:

Bermuda is an Overseas Territory of the United Kingdom, and the Government of the United Kingdom is the sovereign government.[1] Executive authority in Bermuda is vested in the British monarch (currently Charles III) and is exercised on his behalf by the governor of Bermuda.[1] The governor is appointed by the king on the advice of the British Government. Since December 2020, the governor is Rena Lalgie; she was sworn in on 14 December 2020.[78] There is also a deputy governor (currently Alison Crocket).[78] Defence and foreign affairs are the responsibility of the United Kingdom, which also retains responsibility to ensure good government and must approve any changes to the Constitution of Bermuda
