The topic of this thesis is public relations within the Ministry of the Interior ( in the following text: ministry or MUP). The thesis aims to illustrate how transparency is one of the main principles in all democratic and modern country institutions. It is necessary for the Ministry to show consistency in implementing public policies within its scope of work, even in the cases of illegal and negative examples from their own actions. Only this way it will gain the acceptance of the public and achieve a higher level of citizens' engagement in interests that are mutual to citizens and police. While communicating directly with citizens, each individual police and civil servant needs to show professionalism and ethics. That way, they are contributing to building a good public reputation both for the Police and other services within the Ministry. The Ministry has a specific perception. The public perceives the police directly, through contact with police officers. And indirectly, through the image that's been presented in the media. That is why the prerequisite for effective external communication is quality internal communication. By developing professional, responsible, interactive and cultural communication among all employees in indirect contact with the media and direct contact with citizens, the Ministry achieves a partnership between the community and the police in preventing and detecting criminal offenses and contributes to improving the quality of life. The main goal of public relations in the Ministry is to systematically develop professional, responsible, and interactive communication with external and internal participants. As well as a transparent and proactive approach, building trust, gaining understanding, and opening the door to cooperation with the public and thus improving the reputation, image, and identity and the Ministry and the Police.
