The ultra-prestigious Man Booker Prize confers best-in-the-English-language to one novelist per year, but with the awarding organization based in England, the Booker was limited to Commonwealth writers for its first 45 years; the rules didn’t change until 2013. From the Guardian:
Man Booker Prize judge Carmen Callil has resigned in protest after the other two judges decided to give the prize to Philip Roth. She says of Roth, "he goes on and on and on about the same subject in almost every single book. It's as though he's sitting on your face and you can't breathe."
