More than 900 academics have signed a letter condemning the UK government’s decision to block climate scholar Andreas Malm from entering the country. The Swedish writer, known for his book How to Blow Up a Pipeline, was denied entry last week by the Home Office, which stated that his presence “may not be considered to be conducive to the public good”.
The letter describes the move as “a grave violation of academic freedom and freedom of expression”. Malm was scheduled to appear at an event alongside the co-founder of Palestine Action, a group known for direct actions against arms trade and military targets. The ban came without detailed explanation beyond the Home Office’s brief statement.
Malm’s work has attracted controversy for its direct approach to climate activism. How to Blow Up a Pipeline argues for militant tactics as a response to the climate emergency. His invitation to speak at the UK event prompted the government’s intervention, sparking widespread criticism from academic circles.
The signatories to the letter include professors and researchers from across the UK and internationally. They warn that preventing Malm’s entry threatens the ability of scholars to engage in open debate and exchange ideas, especially on contentious political topics.
This is not the first time the UK government has refused entry to individuals involved in activism or political causes. However, the scale of opposition from the academic community is unusual. The letter calls on the Home Office to reconsider its decision and uphold the principles of free expression that academia depends on.
Malm’s exclusion came as the UK faces intensifying debates over climate policy and activism. His presence at the event was expected to provoke discussion about the limits of protest and the role of direct action in addressing the climate crisis.
The Home Office has not provided further comment on the ban or the specific reasons behind it. Malm’s representatives have described the decision as politically motivated.
The dispute raises questions about the balance between security concerns and the right to free speech in the UK. Academics argue that shutting down voices like Malm’s risks chilling effects on research and public discourse around urgent global issues.
The controversy continues as the event scheduled to include Malm proceeds without him. His exclusion has drawn attention to how governments regulate access to public debate and the boundaries of acceptable dissent.
