Question

what is the main role of ruling party (short)

Answer 1

The ruling party or governing party in a democratic parliamentary system is the incumbent political party or coalition of the majority in parliament, that administers the affairs of state. In many other democratic republic countries, the ruling party is the party of the elected president that is in charge of the executive branch of government. Within a parliamentary system, the majority in the legislature also controls the executive branch of government, thus leaving no possibility of opposing parties concurrently occupying the executive and legislative branches of government, such as in an American style presidential system where the party of the president does not necessarily also have a legislative majority.
