So, I knew that Kyriakos Mitsoakis is related to the PM with the same surname (his dad Konstantinos Mitsoakis, PM 1990-1993), but I found out he's also the brother of Dora Bakoyannis (former Mayor of Athens and Foreign Minister) and the uncle of Kostas Bakoyannis (the current Mayor of Athens). Which is weird, but then Greek politics is infamous for being very Happy Families. And then... that his great-grand-uncle was Eleftherios Venizelos, arguably the founder of modern Greece and certainly the founder of the Venizelist tradition today represented by Pasok and Syriza. Like, this is Romanov levels of inbreeding. Imagine if Rishi Sunak's sister was, I don't know, Theresa May, his nephew was Sadiq Khan, his father was John Major and his distant uncle was David Lloyd George.
Not David Lloyd George, but his frenemy Herbert Henry Asquith has a great-granddaughter who is much more famous than most politicians.
