As a result, minorities in certain areas (in and around Brussels and along the language border) claim to be disenfranchised in local government and services. Along with the usual left–right political division, there is also a linguistic division, causing a double party system which complicates coalition creation on the national level. The crisis over the formation of a coalition government in the aftermath of the 2007 elections, coupled with the unsolved problem of the Brussels-Halle-Vilvoorde electoral district and the rise of extremist political parties, has given a fresh impetus to the issue, with recent opinion polls showing sizable support for a partition.
