Wanderlust World Wanderlust World The Prime Minister is the United Kingdom's chief executive—head of government, leader of the executive branch, and the central figure in British politics.
| Powers | Constraints |
|---|---|
| Patronage (ministers, peers, bishops, judges, BBC chair, etc.) | Party discipline / backbench revolts |
| Agenda control (Queen's Speech, legislative program) | Cabinet collective responsibility |
| National security decisions (intelligence, nuclear, deployments) | Parliamentary scrutiny (committees, votes) |
| International representation (G7, NATO, bilateral) | Courts (judicial review, Human Rights Act) |
| Crisis leadership (pandemic, financial, security) | Media, public opinion, elections |
No fixed deputy. Deputy Prime Minister title granted at PM's discretion (currently Oliver Dowden, also Chancellor of Duchy of Lancaster). Not automatic successor.
The PM's authority rests on one foundation: confidence of the House of Commons. Lose that, and you're gone—by resignation, leadership challenge, or election defeat.
