AGE: 58
OCCUPATION: Prime Minister of the United Kingdom
PREVIOUS APPEARANCES ON THE TIME 100:
PRO: A recent high-profile visit with Obama — during which, in a very Say Anything moment, Brown gifted Obama with a pen — gave the Prime Minister a much-needed popularity boost back home.
CON: With skyrocketing unemployment, poor financial oversight and an unpopular Labour Party, Brown is widely viewed within the U.K. as a lame duck.
