Why Elitist Politicians Like Boris Johnson Often Drop Latin Into Their Conversations

When samuel johnson visited paris he worried that his french wasn't good enough, so he spent the whole time speaking in latin. This became a really, really common thing all over europe and is what kind of brought rich europeans together. And quite ironically, now it's the british politicians who aren't particularly keen on europe, who are often dropping latin into conversation. Do we think it maybe works in some way? Don't know. I imagine the end they went.
