A politician is an individual who works actively in politics and is therefore involved in the political life of a particular country. Therefore, a politician is a citizen who dedicates his time to public interests.
In societies based on a democratic system, a politician participates by giving his opinion, trying to impart and share his political philosophy, and participating with his vote.
A politician, therefore, can influence all those decisions that have to be taken to organize issues that directly affect a state’s public interests.
