Irish author Sally Rooney has been advised she "can no longer safely enter the UK without potentially facing arrest" due to her support for the banned organisation Palestine Action.
Palestine Action was proscribed as a terror organisation in the UK in July after the group claimed responsibility for an action in which two Voyager planes were damaged at RAF Brize Norton on 20 June.
Normal People author Rooney said she would continue to be a supporter despite the ban.
After winning the Sky Arts Award for Literature on Tuesday, the Co Mayo writer reiterated her "solidarity with the people of Palestine" in a message read out by her editor at the ceremony in London.
Faber's Alex Bowler said: "I have a few very simple words from her, which she asked me to share.
"'I'm so touched and grateful to receive this prize. I truly loved writing Intermezzo, and it means the world to me to think that it has found some small place in the lives of its readers. Thank you.
"'I wish that I could be with you this evening to accept the honour in person, but because of my support for non-violent anti-war protest, I'm advised that I can no longer safely enter the UK without potentially facing arrest.
"'In that context, I want to thank you all the more warmly for honouring my work tonight and to reiterate my belief in the dignity and beauty of all human life, and my solidarity with the people of Palestine. Thank you.'"
In August, Downing Street warned that Rooney risked committing a terrorist offence after the award-winning author said she would donate earnings from her books and BBC adaptations to support the group, in a piece for The Irish Times.
She provided support for a legal claim by Huda Ammori, the co-founder of Palestine Action, against the Home Office over the decision to proscribe the group under the Terrorism Act 2000.
Earlier in the month, almost 900 demonstrators were arrested at a central London rally protesting against the ban.
