Devolution of executive and legislative powers may have contributed to increased support for independence in the constituent parts of the United Kingdom. The principal Scottish pro-independence party, the Scottish National Party, became a minority government in 2007 and then went on to win an overall majority of MSPs at the 2011 Scottish parliament elections and forms the current Scottish Government administration. In a 2014 referendum on independence 44.7% of voters voted for independence versus 55.3% against. In Northern Ireland, Irish nationalist parties such as Sinn Féin advocate Irish reunification.
