A fake blue plaque? Looks pretty real to me.

I'm still annoyed that the Daily Star keeps getting credit for this joke.

The joke about Truss's premiership having the shelf life of a lettuce was from the Economist. And it wasn't about the 49 days she was PM - it was referencing the seven days or so that Truss was actually in the driving seat, once you take away the mourning period around the Queen's death when nothing could happen, and then the period after the mini-budget when Jeremy Hunt and the grown-ups took charge.

What the Star did was just riff on the Economist's joke by setting up a webcam.
