Free speech campaign group Reporters Without Borders (RSF) is concerned that Government threats to crack down on encryption technology could make it harder for investigative journalists to keep their sources safe.

Prime Minister Theresa May spoke out about the need to “regulate cyberspace” after the 3 June London Bridge terror attack.

RSF London bureau chief Rebecca Vincent told Press Gazette: “Theresa May’s recent comments about the internet are worrying, especially following Amber Rudd’s previous remarks that tools that use end-to-end encryption such as Whatsapp are ‘completely unacceptable'”.
