From The Bookseller:
If the Man Booker Prize does open itself to US writers, the administrators could have a tough job selling the decision to the publishing crowd.
A survey conducted by The Bookseller showed that 85% of respondents were against the reported move, with fears that it would downplay the impact of the prize and marginalise both UK and Commonwealth writers.
. . . .
Respondents to the survey warned that the reported rule changes, would “inevitably push Commonwealth writers off the list”, and that the prize would lose “its intrinsic Britishness”. Another warned that the judges would not be able to read all the submitted titles: “the pool of books from which to choose would be impossible for a jury to get through in the course of one summer”.
