How the UK Prime Minister & Ministers Are Chosen — The Andy Burnham Case
On 20 July 2026, Andy Burnham took office as Britain's new Prime Minister — the UK's 59th PM and the 7th in just a decade — after Keir Starmer resigned. Remarkably, this happened without a general election: Burnham first won the leadership of the governing Labour Party, and was then invited by King Charles III to form a government. This explainer uses that moment to break down exactly how a UK Prime Minister and Cabinet ministers are chosen — and how it compares with India.
What Happened: Burnham Replaces Starmer
Andy Burnham took office on Monday, 20 July 2026, as Britain's new Prime Minister, promising a 10-year plan to restore political stability and revive the economy, while acknowledging that his six predecessors had tried and failed over the past decade. Formerly the Mayor of Greater Manchester — nicknamed the "King of the North" — the 56-year-old is known for his man-of-the-people style. His first pledge as PM was to end street sleeping by homeless people in Britain.
Burnham met the King at Buckingham Palace with his wife, Marie-France van Heel. The King asked him to form a government, and he agreed — in a meeting that directly followed outgoing PM Keir Starmer tendering his resignation to the King. Burnham was then driven to Downing Street, where he made his first speech as PM — without a podium or notes, and with just two microphones.
He called the moment a "circuit breaker for Britain," promising the biggest changes in 40 years, pledging to "put life's essentials back under public control," build more council homes, and help young people into work. He said he would set out a full 10-year plan later this year, with first cost-of-living steps announced within days. Over the weekend he had announced he would scrap Starmer's national digital ID scheme. Several of Starmer's senior team — including Deputy PM David Lammy and Chancellor Rachel Reeves — said they had been removed as Burnham prepared to appoint his own Cabinet.
Britain got a new Prime Minister without holding a general election. This is entirely normal in the UK system: when a sitting PM resigns mid-term, the governing party chooses a new leader, who automatically becomes PM. This is how Theresa May, Boris Johnson, Liz Truss and Rishi Sunak also took office — and now Andy Burnham.
How is the UK Prime Minister Chosen?
The UK has no single written (codified) constitution. The process of choosing a PM runs almost entirely on convention — long-established, unwritten rules. The core convention is simple:
The monarch appoints as Prime Minister the person most likely to command the confidence of the House of Commons — which, in practice, is the leader of the party (or coalition) that holds a majority of seats.
— UK Constitutional Convention
There are therefore two routes to becoming Prime Minister:
Route 1 — After a General Election
When a general election gives a party a majority in the House of Commons, its leader is invited by the monarch to form a government and becomes PM. Example: Keir Starmer became PM in July 2024 after Labour's landslide election win.
Route 2 — Mid-Term, Without a General Election (the Burnham Route)
If a sitting PM resigns or dies between elections, no national vote is needed. The governing party elects a new leader internally, and that new leader becomes PM — because the party still holds the Commons majority. Example: Andy Burnham (2026), after winning the Labour leadership following Starmer's resignation.
By convention, the PM sits in the House of Commons. Burnham had left Parliament in 2017 to become Manchester Mayor, so before he could become party leader and PM, he had to return to the Commons — he won a seat (Makerfield) only weeks earlier. Only then could he take the top job.
How Are Party Leaders Elected? (The Engine Behind Route 2)
Because a mid-term PM change depends on the governing party picking a new leader, the party's own leadership-election rules effectively decide who becomes PM. Each party sets its own process:
- Labour Party: candidates must first secure nominations from a set number of MPs; if more than one qualifies, the winner is decided by a ballot of party members and affiliated supporters (one member, one vote). If only one candidate qualifies, they are elected unopposed.
- Conservative Party: Conservative MPs vote in rounds to narrow the field to two finalists, and the party's wider membership then chooses between them.
In Burnham's case, he ran unopposed for the Labour leadership and was confirmed as leader on 17 July 2026 — which set him on course to become PM three days later.
The Transition of Power: Step by Step
The handover follows a precise, choreographed sequence rooted in convention:
- Outgoing PM resigns: Keir Starmer delivered his final speech outside No. 10 Downing Street ("I go with a smile"), then travelled to Buckingham Palace to tender his resignation to King Charles III.
- Monarch invites the new leader: the new party leader (Burnham) goes to the Palace, and the King asks him to form a government — the moment power formally transfers (traditionally called "kissing hands").
- New PM enters Downing Street: Burnham travelled to No. 10 and delivered his first speech as Prime Minister.
- Cabinet is appointed: the new PM then names their Cabinet and ministers — which is why Starmer's ministers were being replaced the same day.
How Are Other Ministers Appointed?
Once appointed, the Prime Minister builds the government. Ministers are formally appointed by the monarch on the advice of the PM — but in reality, the PM alone chooses them. Key features:
- Drawn from Parliament: ministers must be members of Parliament — mostly from the House of Commons, some from the House of Lords. This fuses the executive and legislature, the hallmark of a parliamentary system.
- The Cabinet: the senior ~20+ ministers form the Cabinet, the top decision-making body, chaired by the PM. Cabinet ministers usually head departments and are called Secretaries of State.
- Great Offices of State: the most senior posts are the Prime Minister, the Chancellor of the Exchequer (finance), the Foreign Secretary, and the Home Secretary. A Deputy Prime Minister may also be named.
- Hire and fire (patronage): the PM can appoint, move or dismiss ministers in a "reshuffle" — which is why Burnham could remove David Lammy and Rachel Reeves and bring in his own team.
- Collective responsibility: all ministers must publicly support Cabinet decisions — or resign. They are collectively answerable to Parliament.
- Individual responsibility: each minister is personally accountable for their department's conduct.
UK vs India: A Quick Comparison
India's parliamentary system is modelled on the UK ("Westminster") system, so the parallels are close — but there are important differences a UPSC aspirant should know.
| Feature | United Kingdom | India |
|---|---|---|
| Constitution | Unwritten / uncodified (conventions) | Written, codified Constitution |
| Head of State | Monarch (King Charles III) — hereditary | President — elected |
| Who appoints the PM | The Monarch | The President |
| Who becomes PM | Leader commanding a Commons majority | Leader commanding a Lok Sabha majority |
| Ministers appointed by | Monarch, on the PM's advice | President, on the PM's advice (Art. 75) |
| Must ministers be legislators? | Yes — Commons or Lords | Yes — must be/become an MP within 6 months (Art. 75) |
| Collective responsibility | To the House of Commons | To the Lok Sabha (Art. 75(3)) |
| Head of State's role | Largely ceremonial / nominal | Largely nominal; real power with PM & Council of Ministers |
The UK reminds us that a Prime Minister is not directly elected by the people — the country votes for a Parliament, the majority party picks a leader, and the head of state formally appoints them. India borrowed this very logic, then wrote it down.

- No election needed: a mid-term PM change happens when the governing party elects a new leader, who then becomes PM — no general election required.
- The core convention: the monarch appoints the person who can command the confidence of the House of Commons — the majority party's leader.
- Party rules decide: Labour and Conservative leadership contests (member ballots, or unopposed) effectively pick the PM; Burnham won Labour's leadership unopposed and had to first return to the Commons.
