British Prime Minister Boris Johnson is set to overhaul the United Kingdom’s treason laws, the Mail on Sunday newspaper reported.

Johnson’s overhaul will see a new Treason Act, a new Espionage Act for tracking foreign agents and a rewriting of the Official Secrets Act to make it suitable for the digital era, the newspaper reported, citing Downing Street sources.

The newspaper described the overhaul as the biggest shakeup of the treason laws since 1695, saying it was being done to counter the threat posed by Russia and China.
