Normal People author Sally Rooney has said she can 'no longer enter the UK safely without facing arrest' due to her support for proscribed terror group Palestine Action.The group, founded in 2020, was banned in July by Home Secretary Yvette Cooper, after claiming responsibility for £7million worth of damage to two Voyager plans at RAF Brize Norton on June 20. The Home Secretary proscribed the organisation under the Terrorism Act of 2000, making it a criminal offence to belong to or support the group. But Ms Rooney, 34, previously declared that she would continue to be a supporter of the group in spite of the ban, stating that she would donate earnings from her books and BBC adaptations to the organisation.Affirming her support for Palestine Action, the Irish writer previously insisted: 'If this makes me a "supporter of terror" under UK law, so be it.'Now, Ms Rooney has stated that she is unable to enter the UK safely due to her support for the organisation. After winning the Sky Arts Award for literature she reiterated her 'solidarity with the people of Palestine' in a message read out by her editor at the ceremony held in London on September 16.Alex Bowler, from publishing house Faber, said: 'I have a few very simple words from her, which she asked me to share.

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.'Ms Rooney then revealed that as a result of her 'support for non-violent anti-war protest, I'm advised that I can no longer safely enter the UK without potentially facing arrest.'Concluding her speech, Mr Bowler read: '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 adaptions 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.At the time, Ms Rooney wrote: ‘My books, at least for now, are still published in Britain, and are widely available in bookshops and even supermarkets.‘In recent years the UK’s state broadcaster has also televised two fine adaptations of my novels, and therefore regularly pays me residual fees.‘I want to be clear that I intend to use these proceeds of my work, as well as my public platform generally, to go on supporting Palestine Action and direct action against genocide in whatever way I can.

Will that have ramifications for her with the BBC?’Earlier this month, almost 900 demonstrators were arrested at a central London rally protesting against the ban.Scotland Yard condemned the 'intolerable' abuse its officers suffered during the rally in Parliament Square, in Westminster, attended by an estimated 1,500 people.
