Police Clear National Security Adviser's Wife Over Palestine Action Post

She wrote a post. The police read it. Two days later they closed the file. But the question of what Britain's terror law now covers does not close with it.

Police Clear National Security Adviser's Wife Over Palestine Action Post

London, United Kingdom — The Metropolitan Police will take no further action against Sarah Helm, wife of the UK's national security adviser, over a social media post referencing Palestine Action. The force said specialist officers assessed the post and found it did not meet the criminal threshold. Helm has not been charged or arrested, and the matter is closed.

The Decision That Took Two Days

The Metropolitan Police set out the timeline in its own words. "On Thursday 15 October, we were made aware of a post on X relating to Palestine Action," a force spokesperson said. "The post was assessed by specialist officers and it was determined that it did not meet the criminal threshold. No further police action will be taken."

That statement came on Saturday 17 October, two days after the post appeared. The force had spoken once before, on Friday 16 October, saying the post was "in the process of being assessed to determine whether any further police investigation may be required." By Saturday the assessment was done and the answer was no.

The Guardian reported its own understanding of why. "It is understood there was insufficient evidence that the post was capable of encouraging support for a proscribed organisation," the paper said. That reason is The Guardian's reporting. It is not part of the Met's statement.

What Sarah Helm Actually Wrote

The post was short. Sarah Helm wrote on X on Thursday 15 October: "God help us authors who support Palestine and Palestine Action."

The Guardian printed a fuller version of the same post: "God help us authors who support Palestine and Palestine Action. Sounds like Adam would have all our books swept off the shelves in a jiffy."

She was replying to broadcaster Adam Boulton, who had described novelist Sally Rooney's support for Palestine as "anti-Jewish," according to The Guardian.

A second post followed on Friday night, reported by The Daily Telegraph. "Thanks to all supporters. As an 83 yr old survivor of the Nakba and one of my many friends in Rafah (now obliterated) said to me when I was last there, 'keep writing Sarah we need all the pencils we can get'."

The Telegraph was careful about what the first post meant. "While Ms Helm's tweet does not directly say that she supports Palestine Action, it has been interpreted as support for the group," the paper noted.

The Man She Is Married To

Sarah Helm is a journalist and author. She is married to Jonathan Powell. They wed in 2007, The Guardian reports.

Powell is the UK's national security adviser. He was appointed in 2024 under Keir Starmer, according to The Guardian, and has continued in the role under Prime Minister Andy Burnham, per The Telegraph and Sky News.

He is a former diplomat who spent a decade as Tony Blair's chief of staff. The Telegraph describes him as Britain's chief negotiator with Israel. He led recent talks over the future of the British consulate in Jerusalem and travelled to Israel earlier this month to negotiate a deal to keep the consulate open as a mission, the paper reports.

Helm has her own record. She was a Sunday Times journalist, diplomatic editor at The Independent, and the paper's Jerusalem correspondent, covering the Middle East for years. She wrote "A Life in Secrets," a 2007 book about the wartime secret agent Vera Atkins, and the play "Loyalty," a fictionalised account of her opposition to the 2003 Iraq war. She is currently writing a book about Gaza.

A Law That Makes Support a Crime

Palestine Action was proscribed as a terrorist organisation in July 2025. Sky News dates the ban to 5 July 2025. The decision was taken by then-home secretary Yvette Cooper.

Under the law, membership of or support for the group is a criminal offence carrying up to 14 years in prison. The proscription followed an incident in which two members vandalised two Voyager aircraft at RAF Brize Norton, causing an estimated £7 million of damage, Sky News reports.

The group was founded in 2020 and ran a campaign of trespass, vandalism and property damage against companies and buildings it claims are linked to Zionism, according to The Telegraph.

It has fought the ban. The High Court ruled it "disproportionate" in February 2026. The Court of Appeal ruled in June 2026 that banning the group was lawful. On 30 July 2026, the Supreme Court said the group's co-founder could challenge the ban.

Arrest Numbers That Do Not Agree

The figures on arrests do not match. Each outlet reports a different total, and none of them reconciles with the others.

Sky News and The National report 3,867 arrests for suspected terrorist activity in the year to June, of which 3,630 — 94 per cent — were linked to supporting the group. In the previous 12-month period, before the ban came into force, 234 terror arrests were made.

The Guardian reported on 16 October that more than 3,700 people had been arrested for backing the group, with more than 2,250 formally charged as terrorists.

Al Jazeera reported more than 3,500 arrests, many for holding up placards, citing the rights group Amnesty International.

The Daily Telegraph reported more than 3,000 arrests for expressing support for the group.

Four totals from four outlets, and no reconciliation. Each carries its own scope: one counts the year to June, one counts charges as well as arrests, one relies on a rights group's tally.

Why This Post Did Not Cross the Line

The Met gave one sentence of reasoning and stopped. It did not say which part of the post failed the test, or what a post would have to say to pass it. The force has not set its reasoning out beyond that sentence.

The threshold, as The Guardian describes it, is whether words are capable of encouraging support for a proscribed organisation. That is a test about what a sentence can do, not about what the person writing it believed.

Read against that standard, the sentence at issue is a lament. It names Palestine Action. It does not ask anyone to join the group, send it money or take action on its behalf. The Telegraph, which has covered the case closely, noted that the post "does not directly say that she supports Palestine Action".

The contrast is where the discomfort sits. Thousands of people have been arrested since the ban, many of them, Al Jazeera reported, for holding up placards, according to the rights group Amnesty International. A placard is also just words.

The Writers Who Signed

Helm's post landed in the middle of a fight among writers. Sally Rooney announced this week that her books would no longer be sold in the UK, and that she would donate earnings from her books and from BBC adaptations of her novels to Palestine Action, the BBC and The Guardian report.

Her publisher Faber determined it could not sell her novels, including "Normal People" and "Conversations with Friends," in the UK. Faber will continue to sell them elsewhere, The Guardian reports. Rooney said she made the decision after learning that passing earnings to her for UK sales could constitute a serious criminal offence.

Hundreds of writers signed an open letter supporting Rooney and Faber. The Guardian reports 419 signatories, among them Ali Smith, Kamila Shamsie, Robert Macfarlane, Jeanette Winterson, Alice Oseman and Nikesh Shukla.

"As authors, illustrators, poets, and editors, we stand with Sally Rooney and Faber Books, and condemn a government whose actions, and inactions, have led to her books being pulled from sale in the UK," the letter said.

The Vetting Question Without an Answer

The Guardian raised the specific question on 16 October. "According to government guidance, being married to a suspected or convicted terrorist would normally result in the revocation of security clearance," the paper reported.

It added: "Under the vetting framework for a job as national security adviser, being married to someone tied to a proscribed terrorist organisation is viewed as creating an automatic, unmitigated national security risk."

Helm has not been charged, arrested or cautioned. The police closed the matter with no further action. No report says Powell's clearance has been reviewed, suspended or revoked.

Downing Street gave a short response. "These views are held by an individual who does not represent the government in any capacity," a spokesman said.

Powell remains in post. He has not resigned, and no statement from him is in the record.

The Supreme Court Test Still Coming

The ban itself is still being fought. Defend Our Juries, which opposes the proscription, said the government will defend it "in the Supreme Court next month." No fixed date has been given.

The group thanked Helm directly. "Thank you to Sarah Helm for defying this absurdly authoritarian ban on Palestine Action," it said. It added: "How can Andy Burnham's government possibly defend this ban in the Supreme Court next month when his own national security adviser's wife has openly defied it?"

Defend Our Juries also said: "We know of 36 people who have been arrested and had their homes raided for similarly expressing support for Palestine Action on social media." That figure is the group's own.

The Campaign Against Antisemitism had pressed for a police investigation. Its spokesman said: "Clearly, the police need to investigate and Sarah Helm must face the full force of the law, just like others who appear to express support for any proscribed terrorist organisation." The group also said Powell "must publicly denounce this rhetoric if he is to continue in post." It did not call for him to be sacked.

What It Means for Everyone Else

The numbers tell the story the law has produced. Thousands of arrests in a year, on four competing counts that do not agree. A 14-year maximum sentence hanging over support for a banned group. A publisher deciding it cannot sell a novelist's books in Britain.

Foreign Secretary Ed Miliband said last month that the government was "looking at" the Palestine Action ban, adding that he did not believe the mass arrests resulting from its proscription were "anyone's intent," Al Jazeera reported.

Against that, a post by the wife of the national security adviser was assessed in two days and found not to meet the criminal threshold. The law remains. The Supreme Court will hear the challenge. The arrests continue. And the question of where the line sits is no clearer than it was on Thursday.
