I'm sorry if it wasn't clear on the wiki. To be precise, I actually read it in this book (https://www.amazon.co.uk/Principles-Comparative-Politics-William-Roberts/dp/1608716791), but I wasn't sure how to cite it properly, so I linked to the man who'd discovered the information in the first place. It's a political science textbook, and you can find this on page 343 in the first paragraph. I'm kind of new to Reddit, so I wasn't sure...
