Key constitutional changes since 2015

  • In 2015, the Conservative Party won the general election, and remained in power until 2024

    • They introduced a range of reforms, some developing existing provisions and some rolling back previous developments

1. Brexit referendum (2016)

What it did

  • A referendum was held on whether the UK should remain a member of the European Union

  • Turnout was around 72%, with 52% voting to leave and 48% voting to remain

Why it was introduced

  • The last referendum on EU membership had taken place in 1975, leading to claims that a renewed democratic mandate was needed

  • Support for UKIP had grown due to its policy of leaving the EU, posing a threat to the Conservative Party

  • As a result, the Conservatives included a referendum pledge in their 2015 manifesto

Impact

  • The UK left the European Union

  • Parliamentary sovereignty was reasserted as EU law no longer had supremacy over UK statute law

Problems

  • The referendum result was close, leaving the country politically divided

  • It left Northern Ireland in a precarious position as the Republic of Ireland remained in the EU

  • This ultimately resulted in the Northern Ireland Assembly being suspended over a failure to reach an agreeable Brexit settlement

2. Wales Act (2017)

What it did

  • Moved Wales from a conferred powers model to a reserved powers model, allowing the Welsh Parliament to legislate on any matter not explicitly reserved to Westminster

Why it was introduced

  • Wales gained primary legislative powers in 2011

  • Moving to a reserved powers model brought Wales closer to the Scottish devolution settlement

Impact

  • The Welsh Parliament was able to legislate over a wider range of policy areas

  • The significance of this expanded power was particularly evident during the Covid-19 pandemic, when Wales adopted different restrictions from England and Scotland

Problems

  • Despite the growth in devolved powers, turnout at Welsh elections has remained low

3. English Votes for English Laws (EVEL) (2015–2021)

What it did

  • Introduced a procedure in the House of Commons giving English MPs a greater say over legislation affecting only England

Why it was introduced

  • Aimed to address the West Lothian Question, where MPs from devolved nations could vote on England-only matters

Impact

  • In practice, EVEL was rarely used due to its procedural complexity

  • Many pieces of legislation that appeared England-only had implications for devolved nations

Problems

  • Fewer than 50 laws were voted on using EVEL procedures between 2015 and 2021

  • EVEL was repealed in 2021, suggesting it failed to provide a workable solution

4. Elections Act (2022)

What it did

  • Introduced a requirement for voters to show approved photographic identification at polling stations

Why it was introduced

  • The government argued the Act would reduce electoral fraud and increase public confidence in elections

Impact

  • The Act raised concerns about disenfranchisement

  • There was a slight reduction in turnout among voters who lacked appropriate ID or arrived at polling stations without it

Problems

  • According to the Electoral Commission, voter fraud in the UK was already extremely rare

  • The Act potentially disenfranchised voters without identification, disproportionately affecting minorities and working-class voters

5. Public Order Act (2023)

What it did

  • Expanded police powers to manage protests

  • Introduced new criminal offences, including ‘locking on

Why it was introduced

  • Responded to disruptive direct action and public order concerns, particularly protests by groups such as Extinction Rebellion and Just Stop Oil

Impact

  • The Act intensified debate over the balance between the right to protest and the need to maintain public order

Case Study

Public Order Act (2023) used against Just Stop Oil

Protesters march with orange banners and signs reading "Just Stop Oil" in a sunny street, advocating against oil use.
  • In October 2023, the Public Order Act (2023) was applied during a Just Stop Oil protest in London

    • Protesters blocked a road near Parliament, disrupting traffic and daily activity

Application of the Act

  • The Metropolitan Police used Section 7 of the Act, which criminalises interference with the use or operation of key national infrastructure, including major roads

    • Police intervened quickly and arrested several activists for disrupting transport

  • This was a significant example of the Act being used in practice

    • It showed how the new law allows police to act earlier and more decisively against disruptive protests than under previous legislation
