Scotland, Wales and Northern Ireland each have their own devolved government or executive, led by a First Minister (or, in the case of Northern Ireland, a diarchal First Minister and deputy First Minister), and a devolved unicameral legislature. However, England, the largest country of the United Kingdom, has no such devolved executive or legislature and is administered and legislated for directly by the UK government and parliament on all issues. This situation has given rise to the so-called West Lothian question which concerns the fact that MPs from Scotland, Wales and Northern Ireland can vote, sometimes decisively, on matters that only affect England.

The Scottish Government and Parliament have wide-ranging powers over any matter that has not been specifically 'reserved' to the UK parliament, including education, healthcare, Scots law and local government. At the 2011 elections the SNP won re-election and achieved an overall majority in the Scottish parliament, with its leader, Alex Salmond, as First Minister of Scotland. In 2012, the UK and Scottish governments agreed on the terms for a referendum on Scottish independence in 2014.

The Welsh Government and the National Assembly for Wales have more limited powers than those devolved to Scotland. The Assembly is able to legislate on devolved matters through Acts of the Assembly, which require no prior consent from Westminster. The 2011 elections resulted in a minority Labour administration led by Carwyn Jones.

The Northern Ireland Executive and Assembly have powers similar to those already devolved to Scotland. The Executive is led by adiarchy representing unionist and nationalist members of the Assembly. Currently, Peter Robinson (Democratic Unionist Party) andMartin McGuinness (Sinn Féin) are First Minister and deputy First Minister respectively.

The UK does not have a codified constitution and constitutional matters are not among the powers devolved to Scotland, Wales or Northern Ireland. Under the doctrine of Parliamentary sovereignty, the UK Parliament could, in theory, therefore, abolish the Scottish Parliament, Welsh Assembly or Northern Ireland Assembly. Indeed, in 1972, the UK Parliament unilaterally prorogued theParliament of Northern Ireland, setting a precedent relevant to contemporary devolved institutions. In practice, it would be highly unlikely that the UK Parliament would ever abolish devolution, given the political constraints created by referendum decisions. The political constraints placed upon the UK Parliament's power to interfere with devolution in Northern Ireland are even greater than in relation to Scotland and Wales, given that devolution in Northern Ireland rests upon an international agreement with the Government of Ireland.
