2007 Ukrainian political crisis

A political crisis in Ukraine occurred between April to June 2007, due to political stand off between coalition and opposition factions of Ukraine's parliament, the Verkhovna Rada, that led to the unscheduled 2007 Ukrainian parliamentary election. It started on 2 April 2007 as a culmination of long lasting crisis and degradation of the parliamentary coalition when the president of Ukraine (Viktor Yushchenko) attempted to dissolve the parliament.
