I remember getting a recommended video on YT about a year ago, that talked about the “secret” plan that is in place should the Queen die. This plan covers a TEN-day period of “mourning and great sorrow”, known as Operation London Bridge.

Unless the plan activates, I expect the old hag to outlive the planet at this rate.
