Which is the only British Prime Minister to serve three monarchs?
user
The only British Prime Minister to serve three monarchs was Stanley Baldwin. He was a kind of big boss, like a school principal, for the United Kingdom. The three monarchs, or kings and queens, he served were King George V, King Edward VIII and King George VI. It's like he was a favorite teacher to three different school principals.
