The Boy in the Stripped Pyjamas author John Boyne has been denied a second literary award after he backed JK Rowling over her gender critical views.

The 54-year-old Irish author was initially offered the James Joyce Award for his novel Earth, which takes on themes of sexual assault and homophobia.

However, the prize offer was withdrawn by University College Dublin's Literary and Historical Society amid a row over an accolade for LGBT writers known as the Polari Prize.

The James Joyce Award was put on hold after over 800 authors signed a petition against his book's nomination after Boyne said he supported Rowling and her criticism of gender ideology.

Opposing authors described his inclusion on the list, which was released on August 6, as 'inexcusable' due to his public comments on trans rights and identity.
