Sarah Helm, a writer and wife of National Security Adviser Jonathan Powell, posted on X: "God help us authors who support Palestine and Palestine Action." The post — responding to the Sally Rooney UK book-sales controversy — is now under Metropolitan Police assessment. The government immediately distanced itself, calling Helm "an individual who does not represent the government in any capacity." That framing will be tested. Palestine Action was proscribed in July 2025 after activists broke into an RAF base and sprayed red paint on two aircraft to protest UK military support for Israel's war on Gaza. Membership or support now carries up to 14 years in prison. Since the ban, police have arrested more than 3,500 people for alleged support — many for acts as minimal as holding placards, according to Amnesty International. The Court of Appeal upheld the proscription in June. The Helm episode exposes the structural contradiction at the heart of mass-proscription enforcement. When the net is cast wide enough to arrest 3,500 people for social media posts and placards, it inevitably catches someone proximate to power. The question then becomes whether the law applies uniformly or whether proximity to the National Security Adviser's household earns a different standard of review. Foreign Secretary Ed Miliband last month acknowledged the government was "looking at" the ban, conceding that mass arrests were not "anyone's intent." That admission is significant — it signals internal government discomfort with the enforcement footprint of its own legislation. But discomfort is not reform. The ban remains in force, the arrests continue, and the Court of Appeal has already validated the legal basis. Defend Our Juries, a UK activist group, noted 36 people have been arrested and had homes raided for similar social media posts. The asymmetry is the story: ordinary citizens face dawn raids for the same category of expression a senior adviser's spouse made publicly on a platform with millions of viewers. Whether Helm faces equivalent consequences will be a test case for whether the proscription regime operates as law or as selective enforcement. The Sally Rooney dimension adds commercial and cultural weight. When a major novelist withdraws books from an entire national market over the right to direct royalties toward a proscribed group, the ban is no longer a narrow counter-terrorism tool — it is reshaping publishing, commerce, and literary culture. The chilling effect extends well beyond the 3,500 arrested. The 20-year trajectory is clear: either the UK narrows the enforcement scope of its proscription regime, or it normalizes a security-state apparatus that criminalizes expression at industrial scale. The Helm case, precisely because of its proximity to power, may accelerate that reckoning.
