A popular author has pledged to use money from the BBC to fund Palestine Action, a proscribed terror organisation.
Sally Rooney said the police should investigate the companies and high-street stores which stock and promote her work if they think she is committing an act of terrorism.
Having been banned by the Government in July, membership and support of Palestine Action, including funding, can now carry sentences of up to 14 years in prison.

The Normal People author made the comments in the Irish Times, and noted it would now be illegal to do so in the UK.
She said her decision to express her support in public came after "more than 500 peaceful protesters" were arrested on August 9.
She added: "If this makes me a 'supporter of terror' under UK law, so be it.
"My books, at least for now, are still published in Britain, and are widely available in bookshops and even supermarkets."

Ms Rooney continued: "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."
The Irish author has previously shown her support for the organisation by writing a witness statement for the High Court in London where the decision to proscribe the group continues to be challenged by one of its founders.
Ms Rooney has also accused the Prime Minister and his Government of taking the "basic rights and freedoms" of British citizens in order to protect its relationship with Israel.

Earlier this year, activists associated with Palestine Action allegedly broke into RAF Brize Norton in Oxfordshire and caused £7million worth of damage by vandalising two military aircraft.
However, Ms Rooney has condemned the decision which puts the organisation in the same bracket as al-Qaeda and Islamic State, and said "an increasing number of artists and writers can no longer safely travel to Britain to speak in public".
In the six weeks since the ban was introduced, the Metropolitan Police have arrested more than 700 people for their association and support for the group, including a woman in Belfast and an Irish citizen.
She called the arrest by the Police Service of Northern Ireland (PSNI) "political policing".

Additionally, Ms Rooney noted the PSNI made no arrests after a mural was repainted in north Belfast last year for the proscribed Ulster Volunteer Force, "responsible for the murders of hundreds of civilians".
She said: "Palestine Action, proscribed under the same law, is responsible for zero deaths and has never advocated the use of violence against any human being.
"Why then are its supporters arrested for wearing T-shirts, while murals celebrating loyalist death squads are left untouched?"
