Constitutional Reform: Current Debates (Edexcel A Level Politics): Revision Note
Exam code: 9PL0
The case for further constitutional reform
Although the UK constitution has undergone significant change since 1997, there is ongoing debate about whether further constitutional reform is necessary
These debates often focus on the balance of power within the UK system, democratic legitimacy and the protection of rights
Arguments to support further reform
1. The House of Lords lacks democratic legitimacy
The House of Lords is an unelected chamber, meaning its members are not directly accountable to the public
In 2023, Boris Johnson’s resignation honours attracted controversy, including the appointment of Charlotte Owen, the youngest life peer in history
This suggested that appointments can appear partisan, strengthening the argument for an elected House of Lords
2. The executive can exercise excessive power (elective dictatorship)
The doctrine of elective dictatorship suggests that governments with strong Commons majorities can dominate Parliament
For example, the Internal Market Bill (2020) allowed ministers to override parts of the Brexit Withdrawal Agreement
The government’s own lawyers warned that this would breach international law, highlighting weak checks on executive power
3. The Prime Minister can abuse prerogative powers
The Prime Minister has significant discretion over prerogative powers, including prorogation
In 2019, Boris Johnson’s prorogation of Parliament was ruled unlawful by the Supreme Court
This exposed gaps and ambiguities in constitutional constraints on the executive
4. The electoral system produces unrepresentative outcomes
The First Past the Post system can produce disproportionate results
This strengthens the case for electoral reform
Case Study
The 2024 general election and minor parties under First Past the Post

The outcome for larger parties
In the 2024 general election, Labour won around 34% of the national vote but secured nearly 64% of the seats in the House of Commons
This shows how FPTP can disproportionately reward the largest party, turning a minority share of votes into a large parliamentary majority
The outcome for smaller parties
By contrast, smaller parties were under-represented:
Reform UK won around 14% of the vote but gained only five seats, because its support was spread thinly across many constituencies
The Green Party won around 7% of the vote but secured only four seats, despite millions of votes nationwide
5. Rights protection is weak and unentrenched
Rights in the UK are not entrenched and can be altered or removed by Parliament
The Rwanda Bill (2024) attempted to declare Rwanda a ‘safe’ country despite Supreme Court objections
This raised concerns about the vulnerability of rights under parliamentary sovereignty
The case against further constitutional reform
Others argue that further constitutional reform is unnecessary and could be damaging
Arguments against further reform
1. The flexibility of the uncodified constitution is a strength
The UK constitution can adapt quickly to changing circumstances
In 2022, three Prime Ministers were replaced lawfully within a short period without constitutional crisis
This demonstrates the adaptability of the current system
2. Existing checks on government already work
The judiciary has shown its ability to restrain executive power
The Supreme Court’s ruling against the 2019 prorogation demonstrated judicial independence and effective constitutional checks
3. Incremental reform has been effective
Devolution settlements have gradually increased powers in Scotland and Wales without destabilising the political system
Rapid or radical reform could risk undermining the unity of the UK
4. There is limited public appetite for major reform
Public support for constitutional change is inconsistent
The 2011 AV referendum resulted in 67% voting against electoral reform
This suggests major reforms may lack democratic mandate
Extending devolution in England
Given the experiences of devolution in Scotland, Wales and Northern Ireland, there have been calls to extend devolution to England through the creation of an English Parliament

Codification of the UK constitution
The UK constitution is uncodified and unentrenched
It is not set out in a single written document and can be changed through ordinary parliamentary procedure
This has led to debate over whether the UK would benefit from adopting a codified constitution, similar to those found in countries such as the USA
Arguments in favour of codification
It would provide greater clarity about the constitutional settlement of the UK, including the rights of citizens, the separation of powers and devolution arrangements
A codified constitution would protect rights more securely, as it would be more difficult to amend or repeal
This would make it harder for governments to remove or weaken rights, strengthening long-term protection
Codification would limit the power of the executive by increasing checks and balances within government
It would encourage long-term constitutional stability by making major changes harder to achieve
Arguments against codification
Codification would weaken parliamentary sovereignty, which has been a central feature of the UK constitution for centuries
It risks giving too much power to judges, who would be responsible for interpreting and enforcing a codified constitution
This could politicise the judiciary, making it more difficult for judges to maintain independence and neutrality
Drafting a single constitutional document would be extremely difficult due to the diverse political identities and constitutional arrangements of the UK’s nations
The loss of flexibility could undermine the UK’s ability to respond quickly to crises
A codified constitution could lead to political deadlock between branches of government with more equal authority
If amendment thresholds were set too high, necessary constitutional reform could become impossible
