Police Assess Social Media Post by Sarah Helm, Wife of UK National Security Adviser, Over Apparent Palestine Action Support

British police are assessing a social media post by the journalist and author Sarah Helm after she appeared to express support for Palestine Action, the pro-Palestinian campaign group that was banned as a terrorist organisation last year, in a development that has thrown a fresh political spotlight on the government of Prime Minister Andy Burnham.

According to Reuters, which first reported the assessment on Friday, Helm — the wife of Downing Street’s National Security Adviser, Jonathan Powell — responded on X to a post about the Irish novelist Sally Rooney, who this week announced that her books would no longer be sold in Britain because she intends to use her royalties to support Palestine Action.

Helm’s post read: “God help us authors who support Palestine and Palestine Action.”

A Metropolitan Police spokesperson said the force had been made aware of the X post, which was published on 15 October, and that it was “being assessed to determine whether any further police investigation may be required”, Reuters reported. The Sun, which broke the story overnight, said the assessment related to a potential breach of terrorism legislation that has made expressing support for a proscribed organisation a criminal offence in Britain since July 2025.

A government spokeswoman distanced the administration from the remarks, telling reporters: “These views are held by an individual who does not represent the government in any capacity.”

A Political Storm at Westminster

The controversy escalated on Thursday night when Danny Kruger, the Reform MP, wrote to Mr Burnham raising concerns about the post. According to The Sun, Mr Kruger said Ms Helm appeared to have breached the law and questioned what influence, if any, she might have on government policy on Israel and Palestine and on the enforcement of the proscription of Palestine Action.

The Sun quoted Mr Kruger’s letter as noting that Jonathan Powell would be well aware that Palestine Action is a proscribed terrorist organisation under the Terrorism Act 2000 and that it has been an offence for anyone in Britain to display support for the group since July 2025. He wrote that he was “alarmed at what influence, if any, she might have on government policy with respect to Israel/Palestine and to the enforcement of the proscription.”

The Times reported that critics were demanding an investigation and said: “This raises extremely serious questions for Jonathan Powell and the government. Spouses are entitled to independent views but plainly Mr Powell, who leads on our country’s national security and has been intricately involved in our Middle East diplomacy, must publicly denounce this rhetoric if he is to continue in post.”

The episode places an unwelcome spotlight on the National Security Adviser’s household. Powell, a former chief of staff to Tony Blair, is one of the most influential figures in the British national security establishment, closely involved in shaping the government’s Middle East diplomacy. The Times noted that his marriage to Helm, in 2007, joined two prominent careers — his in politics and hers in journalism and literature.

Who Are Sarah Helm and Jonathan Powell?

Sarah Helm, born on 2 November 1956, is a British journalist and non-fiction writer who worked for The Sunday Times and The Independent during the 1980s and 1990s. As The Independent’s diplomatic editor from 1989, she covered the fall of the Berlin Wall, the Gulf War and developments in the Middle East, and later covered European affairs in Brussels. Her reporting on the Spycatcher controversy earned her the British Press Award for Specialist Writer of the Year, and in 1987 she won the Laurence Stern Fellowship to work at The Washington Post.

Helm’s books include A Life in Secrets: The Story of Vera Atkins and the Lost Agents of SOE, published in 2005 to acclaim in The New York Times and The Washington Post, and If This Is a Woman: Inside Ravensbruck, Hitler’s Concentration Camp for Women, published in 2015. Her play Loyalty, a semi-fictional treatment of the Iraq War, premiered in 2011. According to The Times, Helm has also written Gaza: The Long Road to Destruction, 1870–2024, a history of the Gaza Strip released last month that places the current conflict in a century-long context.

Jonathan Powell served as Tony Blair’s chief of staff from 1997 to 2007, making him one of the longest-serving and most powerful Downing Street advisers of the modern era. He is now the Prime Minister’s National Security Adviser, a role that places him at the centre of decisions on counter-terrorism policy — including the very proscription regime under which Palestine Action was banned.

The Rooney Trigger

The immediate trigger for Helm’s post was the dramatic announcement on Wednesday by Sally Rooney that her books would no longer be sold in Britain over her support for Palestine Action. Rooney, the bestselling author of Normal People and Conversations with Friends, has been a vocal supporter of the group, including after its proscription by the British government under terrorism laws last year.

Rooney and her publisher, Faber, said they had agreed that “we can no longer supply her works in the UK in any format”, though Faber would continue selling her work elsewhere. Faber said in a statement: “Current legislation in the UK has led to circumstances where Faber cannot pass on UK earnings to Sally Rooney for her work. To sell a writer’s work and not be able to pass on earnings is an unconscionable situation for a publisher.”

Rooney had previously said in a witness statement submitted to London’s High Court, in support of a legal challenge over the ban on Palestine Action, that her plans to use her royalties to support the group could lead to her books being withdrawn from sale in Britain. “I have made every effort to be honest with the public about my beliefs and intentions and I am wholly prepared to accept the consequences,” she said in her statement on Wednesday, according to Reuters and CNN.

The Times reported that a legal expert said it was highly unlikely Rooney’s announcement was a publicity stunt, pointing to Section 17 of the Terrorism Act 2000, which creates an offence of being involved in a “funding arrangement” with a proscribed group. The same expert said Rooney’s publisher could face problems with its own bank: “There would be the chance that the publisher could be debanked.”

The affair has sent shockwaves through the publishing industry. Kate Clanchy, whose own book was withdrawn in 2022 after accusations of racist tropes, told The Times that Rooney’s decision risked encouraging other writers to take similar action, asking: “How many writers will feel the pressure to make similar pledges? How many publishing houses can weather the pressure? How many bookshops will go under? How many advances for new writers will be lost?”

How Palestine Action Came to Be Banned

Palestine Action, which had increasingly targeted Israel-linked defence companies with direct-action protests, was proscribed by the government shortly after a June 2025 break-in at the Royal Air Force’s Brize Norton base, Reuters and CNN reported. The group has carried out protests including vandalism in support of Palestinian causes, and denies that its actions amount to terrorism.

Four members of the group were jailed in June over a 2024 raid on a factory operated by the Israeli defence firm Elbit Systems, which caused more than £1 million of damage, Reuters reported. The group’s co-founder, Huda Ammori, challenged the proscription: the High Court ruled in her favour in February, before the Court of Appeal overturned that decision in June. The Supreme Court is due to hear an appeal next month.

Amnesty International says more than 3,500 people have been arrested in Britain for alleged support of Palestine Action since it was banned last year, many of them for holding up placards, according to Reuters. Civil liberties groups have criticised the proscription, arguing that applying terrorism law to a protest movement — including to people holding signs — is disproportionate and threatens freedom of expression.

Ministers, however, have said the group commits acts of terrorism. The Sun reported that support for Palestine Action became a crime last year and that the government justified the ban on the grounds of its campaign of property damage against defence-linked firms.

Analysis: Why It Matters

The police assessment of Sarah Helm’s post is significant not because of the legal odds of a prosecution — a short social media remark expressing solidarity is far from the clearest case under terrorism law — but because of what it reveals about how Britain’s proscription regime is now operating. When the Terrorism Act 2000 was drafted, its provisions on proscribed organisations were aimed at groups engaged in or preparing acts of serious violence. The question the Helm case forces into the open is whether those same provisions can be sensibly applied to an acclaimed novelist’s wife posting sympathy online.

The institutional dimension is equally awkward. Jonathan Powell does not merely work for the government; he leads the national security apparatus whose policies determine which groups get proscribed and how counter-terrorism law is enforced. The government has said his wife’s views are her own and do not represent it in any capacity. That is formally correct, but it cannot fully dissolve the political problem: the country’s top security adviser is now connected, however indirectly, to an alleged breach of the terrorism law he helps administer. Mr Kruger’s demand that Powell “publicly denounce this rhetoric if he is to continue in post” shows how the opposition will exploit that seam.

There is also a wider chilling effect to consider. The Rooney episode demonstrates that terrorism law is now reaching directly into the economics of publishing: a major publisher has withdrawn one of Britain’s most famous living authors from the domestic market because passing on her royalties could constitute an offence. Helm’s post, in turn, shows that even discussing that development in sympathetic terms can invite police scrutiny. When journalists, publishers and bookshops begin to treat support for a proscribed group as a subject that cannot safely be mentioned, the boundary between countering terrorism and suppressing expression has shifted — whether or not that shift was intended.

The government’s own conduct invites scrutiny as well. The prosecution threshold for offences of expressing support has in practice fallen very low — thousands of arrests, many for placards — while the group continues to challenge its ban in the courts. The Supreme Court hearing next month will be the first time the highest court has examined whether the proscription of Palestine Action was lawful. If the court upholds the Court of Appeal, the ban stands and the enforcement regime continues as it is. If it does not, thousands of arrests may rest on a ban that should never have been made — a prospect that explains why ministers have so far defended the proscription in uncompromising terms.

Finally, there is the human dimension. Helm is not a random social media user; she is a journalist who has spent a career documenting state violence, from the Nazi camp at Ravensbruck to the occupation of Gaza. Her post was plainly a statement of solidarity with authors under pressure, written in response to Rooney’s exclusion from the British market. That a figure of her standing now faces the possibility of a terrorism investigation says as much about the breadth of the law as it does about her politics.

What to Watch Next

1. The Met’s assessment: whether the police decide the post warrants a formal investigation — or drop the matter. The tone of the initial statement suggests a cautious, preliminary process.
2. The Supreme Court appeal: the hearing next month on the lawfulness of the proscription could transform the entire legal landscape, including thousands of existing arrests.
3. Powell’s position: whether Downing Street requires its National Security Adviser to comment publicly, and whether the opposition presses the issue into a wider test of ministerial standards.
4. The publishing fallout: whether other authors or publishers follow Rooney’s lead or the industry lobbies for clearer guidance on the funding-offence provisions.
5. Parliamentary pressure: whether MPs use the episode to reopen debate on the scope of proscription powers under the Terrorism Act.
