The Executive & Parliament (Edexcel A Level Politics): Revision Note
Exam code: 9PL0
The Executive and Parliament
The relationship between the executive and Parliament is central to the UK political system
Parliament is legally sovereign and is intended to hold the executive to account
However, because the executive is usually drawn from the largest party in the House of Commons, it often dominates Parliament in practice
How Parliament holds the executive to account
A key role of Parliament is to hold the executive accountable for its actions, usually through scrutiny
This can occur in a number of ways

1. Legislative control
Parliament must pass Acts to authorise certain executive powers
After the Supreme Court’s decision in Miller v Brexit Secretary (2017), Parliament passed the necessary Act to authorise EU withdrawal under Article 50
However:
due to fused powers in the UK, the government usually holds a majority in the House of Commons
this makes it possible for the executive to pass legislation with relative ease
2. Questioning and scrutiny
MPs can challenge ministers and force them to defend their policies
Methods include:
Prime Minister’s Questions
urgent questions
select committees
parliamentary debates

The balance of power between Parliament and the executive
The balance of power between Parliament and the executive is not static. It varies with governments and national circumstances
Key changes
Since 2009, there has been a rise in judicial review and court challenges
Miller v Brexit Secretary (2017) strengthened parliamentary sovereignty
Reduction in prerogative dominance
Miller v PM (2019) limited the power to prorogue Parliament
Increased assertiveness of the House of Lords
Strong opposition to the Rwanda Bill
National crises can shift power
Covid-19 increased executive dominance
Partygate led to intense scrutiny and Johnson’s resignation
MPs now make greater use of procedures such as urgent questions
Overall assessment
Parliament remains legally sovereign
The executive often dominates Parliament in practice
However, scrutiny mechanisms mean executive power is not unchecked
The relationship between Parliament and the executive is therefore best understood as executive dominance constrained by parliamentary scrutiny
