Devolution in the UK has resulted in distinct legislatures and governments in Scotland, Wales and Northern Ireland, which have powers over a range of policy areas which had previously been the preserve of the UK Government
Promise made by the leaders of the Conservative, Labour and Liberal Democrat parties during the 2014 Scottish independence referendum that the Scottish Parliament would gain further additional powers beyond the Scotland Act of 2012 if Scotland voted to remain within the UK
Scottish Parliament received additional powers and control over all rates and bands for Scottish Income Tax, VAT receipts, welfare and benefits
Scotland now retains half of all VAT receipts and is allowed to top up welfare benefits and create new payments
Scottish Government and Scottish Parliament are now recognised as permanent parts of the constitution, with a referendum required before either can be abolished
Scottish Parliament has control over abortion laws and enhanced powers over welfare, including the ability to top-up any cuts to tax credits made by the UK government
The UK Parliament is responsible for defence. This means that the UK Parliament makes decisions about how best to protect the UK against terrorist attacks. The UK Parliament passed the 2015 Counter Terrorism and Security Act which prevents individuals travelling abroad to engage in terrorist activities.
During the Covid 19 pandemic in 2020 the Scottish Parliament enforced different regulations to those deployed in other parts of the UK. Restrictions on some aspects of lockdown were lifted (eg, opening bars and restaurants) at a later date in Scotland than in England. Restrictions placed on foreign travel were in some cases also different from the other home nations.
A system of increased (or maximum) devolution in Scotland
Holyrood would have power over most reserved matters, except defence and foreign affairs
Holyrood would take charge of all domestic expenditure, including welfare, employment, transport and broadcasting policy
Scottish Parliament would receive all taxes raised in Scotland, making it fully responsible for spending in Scotland
Scottish Parliament would make payments to the UK government to cover Scotland's share of the costs for UK-wide services like defence, national security and conducting foreign affairs
Scottish Parliament would have the right to speak directly on devolved matters, such as fisheries policy
Recommended further devolved powers for Scotland and that the Scottish Parliament and Scottish Government should be recognised as permanent institutions
Created substantial new powers for Scotland, including additional powers and control over all rates and bands for Scottish Income Tax, VAT receipts, welfare and benefits
Scottish Parliament given control over abortion laws and enhanced powers in respect of welfare, including the ability to top-up any cuts to tax credits made by the UK government
The UK government claimed the Scotland Act 2016 has made the Scottish Parliament the most powerful devolved assembly in the world and that promises (the Vow) made before the referendum, had been delivered in full
Those continuing to seek Scottish independence felt the extra powers contained within the Scotland Act 2016 fell short of what was promised before the referendum
Greater devolution in Scotland would inevitably lead to significant constitutional changes
Following devolution, Scottish MPs retained the right to vote in Westminster like any English MP, but English MPs were no longer allowed to vote on a number Scottish devolved policy areas
Many MPs representing constituencies in England called for legislation where only English MPs could vote on English laws (EVEL)
A form of EVEL was introduced in 2015 whereby any law being discussed at Westminster which would affect only England would need to be approved separately by a majority of English MPs, in addition to being passed by the House of Commons as a whole
The decision-making powers held by the Welsh and Northern Ireland Assemblies were also reviewed in light of the new powers granted to Scotland
