The Government of Ireland Act 1920 was an act of the Parliament of the United Kingdom. The Act's long title was "An Act to provide for the better government of Ireland"; it is also known as the Fourth Home Rule Bill or (inaccurately) as the Fourth Home Rule Act and informally known as the Partition Act. The Act was intended to partition Ireland into two self-governing polities: the six north-eastern counties were to form "Northern Ireland", while the larger part of the country was to form "Southern Ireland". Both territories were to remain part of the United Kingdom of Great Britain and Ireland and provision was made for their future reunification through a Council of Ireland. The Act was passed by the British Parliament in November 1920, received royal assent in December and came into force on 3 May 1921.
The West Lothian question, also known as the English question, is a political issue in the United Kingdom. It concerns the question of whether members of Parliament (MPs) from Northern Ireland, Scotland and Wales who sit in the House of Commons should be able to vote on matters that affect only England, while neither they nor MPs from England are able to vote on matters that have been devolved to the Northern Ireland Assembly, the Scottish Parliament and the Senedd. The term West Lothian question was coined by Enoch Powell MP in 1977 after Tam Dalyell, the Labour MP for the Scottish constituency of West Lothian, raised the matter repeatedly in House of Commons debates on devolution.

Since 1998, Northern Ireland has devolved government within the United Kingdom. The government and Parliament of the United Kingdom are responsible for reserved and excepted matters. Reserved matters are a list of policy areas, which the Westminster Parliament may devolve to the Northern Ireland Assembly at some time in future. Excepted matters are never expected to be considered for devolution. On all other matters, the Northern Ireland Executive together with the 90-member Northern Ireland Assembly may legislate and govern for Northern Ireland. Additionally, devolution in Northern Ireland is dependent upon participation by members of the Northern Ireland Executive in the North/South Ministerial Council, which co-ordinates areas of co-operation between Northern Ireland and the Republic of Ireland.
