The UK’s domestic security service, MI5, warned politicians and their staff that they are being targeted by spies from China, Russia and Iran in efforts geared toward undermining British democracy.

The warning, which follows the collapse of an espionage case that has put Prime Minister Keir Starmer’s handling of national security under scrutiny, comes in new guidance published Monday for people working in British politics about how to counter “espionage and foreign interference.”
