Coalition government is the European norm
The recent agreement between the two major Greek political parties to form a transitional coalition government that would lead the country to elections on February 19th, although it is considered a rare political event in Greek politics, on a European level, it is rather the rule than the exception, as evidenced by research on the type of party politics in the 27 member states of the European Union.
Moreover, according to data available for the statehood of the European countries from 1945 till today, only Spain, Greece and Britain seem to have no significant experience in this type of government, unlike the Netherlands, Luxembourg and Germany where it is the dominant model.
