Norwegian politicians are required by law to only use official channels of communication (government email, phone etc) when discussing anything related to their public service. Citizens can demand to get access to these communications, even anonymously. This has made it possible for regular citizens to uncover both small and big abuses of power through the years, most recently exemplified by a close connection between the Police and a private anti-drug-lobby organization that has had a big influence on drug policy for decades.
I have, however, heard that apps like Signal has become more common among politicians, but using it for official business is still illegal.
