Radio Caroline, a local radio station in Essex, England, mistakenly broadcast a scripted alert announcing the death of King Charles III [1].

The incident highlights the risks associated with automated broadcasting systems and the potential for widespread misinformation when pre-written emergency protocols are triggered without human oversight.

The erroneous announcement occurred on May 19, 2024 [1]. The broadcast utilized a specific "Death of a Monarch" procedure, a pre-written script designed for use upon the actual death of the sovereign [1], [2].

Station officials said a computer error triggered the alert [1], [2]. The mistake led to the false report that the King had died, causing immediate confusion among listeners in the Essex region [1], [3].

Radio Caroline issued an apology following the broadcast [1]. The station said the technical glitch was the sole cause for the activation of the script [2].

Broadcasters in the United Kingdom often maintain detailed contingency plans for the death of a monarch to ensure a seamless transition of news and music during the national mourning period. In this instance, the automation intended for a national crisis instead created a localized panic [1], [3].

“A computer error triggered the station’s pre‑written 'Death of a Monarch' procedure.”

This event underscores the tension between the necessity of prepared emergency protocols and the fragility of the software that manages them. While 'Death of a Monarch' scripts are standard operational requirements for UK broadcasters, the lack of a manual 'kill switch' or verification step in this case allowed a technical error to mimic a historic national event, demonstrating how automation can bypass editorial judgment.
