Today, Scotland, Wales and Northern Ireland each possess a legislature and government alongside that of the United Kingdom, responsible for devolved matters. However, it is a matter of dispute as to whether increased autonomy and devolution of executive and legislative powers has contributed to a reduction in support for full independence. The principal pro-independence party, the Scottish National Party, won 20 extra MSPs at the 2007 Scottish parliament elections and now forms the Scottish Government as a minority administration, with plans to hold a referendum on negotiating for independence. In Wales, the nationalist party, Plaid Cymru, is the junior coalition partner in the Welsh Assembly Government although unlike the Scottish National Party it does not officially advocate complete secession from the United Kingdom.
