<!--
'''Büyük koalisyon'''<!-- is an arrangement in a [[multi-party]] [[parliamentary system]] in which the two largest [[political party|political parties]] of opposing [[political spectrum|political ideologies]] unite in a [[coalition government]]. The term is most commonly used in countries where there are two dominant parties with different ideological orientations, and a number of smaller parties that have passed the [[election threshold]] to secure representation in the [[parliament]]. The two large parties will each try to secure enough seats in any [[election]] to have a [[majority government]] alone, and if this fails each will attempt to form a coalition with smaller parties that have a similar ideological orientation. Because the two large parties will tend to differ on major ideological issues, and portray themselves as rivals, or even sometimes enemies, they will usually find it more difficult to agree on a common direction for a combined [[government]] with each other than with smaller parties.
