North Korea is technically a multi-party state since other parties do exist besides the Korean Workers' Party (KWP). However, the KWP also controls the other parties so it can stay in power. The constitution claims that North Korea's citizens have freedom of speech, religion and press. In real life, these citizens do not have these rights. People can be jailed if they criticise the party, government, or leaders. North Koreans are encouraged to report family members to the police if they think they are doing something illegal. In return they get more privileges. If someone is caught doing a crime, their whole family will be sent along with them to a labour camp. Most die there, but a few escape.
