Prime Minister and cabinet power
Traditionally, the Prime Minister has been described as first amongst equals
This means the Prime Minister is the most senior member of the Cabinet but is expected to work collectively with other ministers
Decisions are meant to be discussed and agreed through Cabinet government
In recent years, it has been argued that the UK is moving towards presidential government
This term suggests the Prime Minister has become too powerful, similar to the President of the United States
Prime Ministers now have greater control over:
Media appearances
Policy announcements
Cabinet appointments and dismissals
Sofa government
The term sofa government refers to decision-making that happens informally
Instead of full Cabinet discussions, decisions are made through private conversations with a small group of advisers or ministers
This style of leadership has been criticised because:
It reduces transparency
It weakens collective responsibility
Other Cabinet ministers may feel excluded or undermined
Limits on Prime Ministerial power
Although the Prime Minister appoints the Cabinet, they do not have unlimited power
Cabinet ministers can:
Leak disagreements to the media to weaken the Prime Minister’s authority
Threaten to resign, which can damage public confidence
If enough senior ministers resign, the Prime Minister may be forced to step down
Case Study
Boris Johnson

Leadership style
Boris Johnson, Prime Minister from 2019 to 2022, was often described as using a presidential style of leadership
Critics argued he relied heavily on advisers and informal decision-making
In 2022, Johnson faced growing criticism over:
Leadership style
Trust and standards in public office
The outcome
A wave of ministerial resignations followed
Over 60 government ministers resigned, including senior Cabinet members such as the Chancellor of the Exchequer and the Health Secretary
These resignations made it clear that Johnson had lost the confidence of his Cabinet
As a result, Boris Johnson was forced to resign as Prime Minister
