Tensions over the decision to allow US authors to enter the Man Booker prize have flared up yet again, with 30 publishers signing a letter urging the prize organisers to reverse the change, or risk a "homogenised literary future".
The letter, which was intended to be private and has been seen by the Guardian, argues that the rule change to allow any writer writing in English and published in the UK to enter has restricted the diversity of the prize and led to the domination of American authors since it came into effect in 2014. Previously, the prize only allowed citizens from Commonwealth countries and the Republic of Ireland to enter.
