In NLJ this week, Sailesh Mehta and Theo Burges of Red Lion Chambers examine the government’s first-ever 'Afghan leak' super-injunction—used to block reporting of data exposing Afghans who aided UK forces and over 100 British officials. Unlike celebrity privacy cases, this injunction centred on national security. Its use, the authors argue, signals the rise of a vast new body of national security law spanning civil, criminal, and media domains

The 2023 National Security Act broadened offences, but geopolitical volatility from Russia, China and Iran has driven even more cases. Mehta and Burges warn that practitioners now need multidisciplinary expertise—from espionage to press law—to navigate this expanding field.

The Afghan case, they conclude, epitomises a legal 'hydra' growing new heads with every global crisis.
