Anyone who pays any attention knows Boris is a liar and a fraud but there's millions of people who don't pay attention who vote for him because he comes across to them as a friendly, somewhat eccentric, affable character who they feel gets a hard time and is doing his best (e.g. my mother-in-law). Anything that raises his profile as an out and out liar, bullshitter and danger to the nation has got to be a good thing even if it only gets through to a few of the people who vote for him. They certainly aren't listening to Starmer however much he calls him out in proper parliamentary language on a Wednesday.
