The December 2019 Queen Elizabeth II Twitter Death Rumour was sparked by a viral screenshot of a WhatsApp group chat named 'Gibraltar,' which claimed the monarch had suffered a heart attack. The message even detailed 'Operation London Bridge' protocols, leading many social media users to believe the news was real until Buckingham Palace officials eventually clarified her status. The incident quickly transformed into a massive meme trend, with users poking fun at the 'leaker' and the Queen's legendary longevity. Today, it serves as a classic example of internet misinformation culture and the common trope regarding the Queen's perceived immortality, frequently used to mock people who fall for unverified viral news.
