Boris never changed his mind, he knew Brexit was bad but used it for political gain.

It’s an amazing butterfly effect - how something seemingly small - Angus Deyton doing hookers and blow - led to Boris Johnson’s popularity on a panel show which led to his London mayorship and antics which endeared him enough to be able to swing enough votes during Brexit to sway one way or another.

I'm not sure cause and effect on that: https://benwheatley.github.io/blog/2024/04/07-12.47.14.html

But I also find it odd that Johnson became a guest host a few episodes after Deyton was kicked off in 2002. Was Johnson's adulterous nature not known at the time? Johnson's cocaine stories were, I think, 2005 (on the show itself), 2007, and 2019, and he hosted again in 2003, 2005, and 2006, at least the last of those should not have happened on the basis of the argument used against Deyton.
