Met Police Assess Post by National Security Adviser’s Wife Supporting Proscribed Group

Key points

• Metropolitan Police are assessing a post by Sarah Helm referencing Palestine Action to determine if an investigation is required.
• Helm’s post supported author Sally Rooney, whose books were withdrawn from UK shelves after she pledged royalties to the group.
• Downing Street stated Helm’s views are personal and do not represent the government, but critics argue Powell must denounce them to retain his post.
• The proscription of Palestine Action in 2025 has resulted in over 3,700 arrests, with a legal challenge pending in the Supreme Court next month.
• Government vetting guidelines suggest that being married to a supporter of a proscribed group creates an automatic national security risk.

Background

This incident occurs against the backdrop of the UK government’s 2025 proscription of Palestine Action, which the Home Office labeled a terrorist organization. The ban made support for the group a criminal offense punishable by up to 14 years in prison. Jonathan Powell, appointed by Keir Starmer in 2024 and retained by Andy Burnham, serves as the national security adviser. The archive notes that while US national security structures have seen consolidation of power, the UK case focuses on the personal vetting standards for senior advisers.

How outlets are covering it

Outlets diverge on the implications of the post. The Campaign Against Antisemitism called the post 'gobsmacking' and demanded Powell publicly denounce the rhetoric to keep his job, arguing it compromises Middle East diplomacy. Conversely, Green Party leader Zack Polanski commended Helm for 'bravery' and called the proscription 'ludicrous and authoritarian.' The Guardian emphasized the legal risk, noting that government guidance views marriage to a supporter of a proscribed group as an unmitigated security risk. Al Jazeera highlighted the broader context of mass arrests, noting Amnesty International reports that many arrests were for holding placards. Defend Our Juries argued the incident exposes the 'absurdity' of a ban that cannot be universally enforced, citing 36 other arrests for similar social media posts.

Why it matters

The case tests the boundaries of free speech versus national security vetting in the UK. If Powell is forced to resign or the post leads to prosecution, it could set a precedent for the enforceability of the Palestine Action proscription. The pending Supreme Court challenge to the ban adds urgency, as the government must defend its legal basis while facing internal scrutiny over the conduct of its top security adviser’s family.

What to watch

The Metropolitan Police will determine if the post warrants a formal investigation. The Supreme Court is scheduled to hear the legal challenge to the proscription of Palestine Action next month. The government may need to address whether Powell’s security clearance remains valid given the vetting guidelines regarding spouses of proscribed group supporters.
