Novelist Sally Rooney has vowed to fund the proscribed terror group Palestine Action.

The Normal People author said she would donate earnings from her books and BBC adaptations to the organisation, adding: ‘If this makes me a “supporter of terror” under UK law, so be it.’

Funding terrorism carries up to 14 years’ imprisonment under the Terrorism Act 2000 – the same piece of legislation used to ban Palestine Action last month.

Ms Rooney, 34, wrote in an article for The Irish Times: ‘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.
