I think they were taken by the sound-alike Liz Truss/lettuce.

unless the lettuce is wet?

The Daily Star (a fairly low-rent tabloid newspaper in the UK) has been live-streaming a video of a lettuce for most of the week, as a competition to see whether Liz Truss will resign, or the lettuce reach its best-before date (10 days) first.

In addition to other comments, I suspect that the livestreamed lettuce was a reference to an earlier article saying describing Truss as having effectively had seven days in power before everything fell apart, saying "That is roughly the shelf-life of a lettuce." - various other media outlets seemed to pick up & run with the lettuce reference.

Someone set up youtube stream with a picture of Liz Truss and a lettuce. People in the chat could discuss what was likely to last longer, the lettuce or Liz Truss.

That newspaper started a live feed pitting a lettuce against the PM seeing if she could last longer in office than the lettuce.
