Description
In recent years, we have seen proscription used increasingly on a wider range of organisations. Exploring the case of the United Kingdom, the article delves into the widening of proscription from Hamas’ political wing in 2022, to the listing of Hizb-ut-Tahrir in 2024 and Palestine Action in 2025. While proscription has always shaped and reinforced a specific definition of terrorism, the article argues that these new linkages have untethered the connection between proscription and terrorism. The article reflects on how advocacy groups are navigating this liminal space, one in which showing ‘support’ for a proscribed organisation or analogous political objectives makes them terrorists. In doing so, the article contributes to this special issue on proscription by examining its expanding scope, which increasingly encompasses new targets and emerging issues.
