King Charles III exercises one of the British monarchy's most significant remaining personal powers through his constitutional right to appoint a new prime minister. This prerogative stands as a rare instance where the sovereign acts independently, without requiring ministerial advice or consulting others before formally inviting a politician to form a government. The appointment marks a pivotal moment in British constitutional practice, blending modern political reality with centuries of royal tradition.
While the monarch technically holds absolute discretion in choosing who may lead the government, this power operates within strict constitutional boundaries. The appointee must command the confidence of the House of Commons, which in practical terms means holding or being able to secure an overall majority of seats in Parliament. This requirement ensures that the monarch's choice aligns with parliamentary will, preventing the sovereign from arbitrarily installing a prime minister lacking democratic support. The constraint transforms what appears as unlimited royal power into a carefully circumscribed constitutional function.
In navigating this delicate appointment process, the monarch may seek guidance from various quarters while maintaining political neutrality. The outgoing prime minister, rival party leaders, senior members of the Privy Council, and other trusted advisors can offer counsel, but the final decision rests entirely with the sovereign. This consultation phase allows the monarch to gather intelligence about which candidate genuinely possesses parliamentary support and best serves the interests of stable government, though the sovereign must exercise discretion and caution throughout.
The appointment of a successor to Keir Starmer will follow a prescribed ceremonial and constitutional sequence. Starmer must first meet King Charles III in person to formally tender his resignation during a private audience, adhering to tradition that requires the outgoing premier to resign directly to the monarch rather than through written communication. This personal encounter, conducted in private, marks the formal end of his tenure as prime minister. Only after the Labour Party selects its new leader will that individual be summoned for their own audience with the King.
During the audience appointing the new prime minister, formal rituals dating back generations take place. The ceremony traditionally involves what is termed "kissing hands," though as Tony Blair famously discovered before his 1997 appointment, the actual practice involves merely brushing the monarch's hands gently with one's lips rather than a full kiss. Male prime ministers typically bow during this moment, while female prime ministers may curtsy if they choose. These gestures, seemingly quaint in modern politics, carry symbolic weight as physical acknowledgement of the sovereign's constitutional authority to appoint government leaders.
The anecdote from Blair's experience illustrates how these traditions can produce unexpected moments despite their formality. An official had warned him beforehand about the proper protocol for the hand-kissing ceremony, yet in his nervousness, Blair tripped on carpet and, as he later recounted, practically enveloped rather than brushed the Queen's hands. The late Queen Elizabeth II reportedly remarked on his "enthusiasm," demonstrating the human side of even the most formal constitutional moments. Such stories underscore that beneath the ceremonial trappings lies genuine interaction between the monarch and the nation's political leaders.
The actual physical kissing of hands now typically occurs later during a Privy Council meeting rather than during the initial appointment audience. When a newly appointed prime minister is sworn in as First Lord of the Treasury or becomes a new Privy Counsellor, the kissing of hands ceremony takes place in that formal context. This separation of the symbolic gesture from the initial appointment audience reflects evolution in constitutional practice while maintaining the ceremonial tradition.
Once appointed, the prime minister enters into a distinctive working relationship with the monarch. The prime minister holds a private weekly audience with King Charles III each Wednesday following Prime Minister's Questions in Parliament to discuss matters of government business. These confidential meetings provide the monarch an opportunity to stay informed about government operations and, if necessary, to advise or warn the prime minister about concerns. The weekly audience represents a crucial channel through which the sovereign, while scrupulously maintaining political neutrality on partisan matters, can exercise significant informal influence over the government.
King Charles III will become the fourth monarch of his reign to appoint a new prime minister, following Liz Truss, Rishi Sunak, and Keir Starmer. This frequency of change in recent years stands in sharp contrast to longer periods of stability earlier in his mother Queen Elizabeth II's reign. Each appointment involves the same constitutional procedures and ceremonial elements, yet the rapidity of succession creates a distinctive moment in contemporary British politics. The new appointment will be formally recorded in the Court Circular, the daily official record of royal engagements, noting that the incoming prime minister "kissed hands" upon receiving the monarch's commission to form a government.
The constitutional role of appointing prime ministers represents a delicate balance in the British system of government. The monarch's personal prerogative remains theoretically broad, yet operates within practical constraints imposed by parliamentary democracy and constitutional convention. This arrangement has endured because it preserves the symbolic authority and dignity of the Crown while ensuring that real power flows through elected representatives. The appointment ceremony and its attendant rituals serve to remind both the monarch and the prime minister of their respective roles within a constitutional framework where sovereignty and democracy must coexist.
For Commonwealth observers, including those in Malaysia and other nations with inherited Westminster traditions, the British appointment process offers insight into how constitutional monarchies manage the transition of executive power. The careful balance between royal prerogative and parliamentary reality reflects principles embedded in many inherited constitutional systems across the Commonwealth. Understanding how King Charles III exercises this appointment power illuminates enduring questions about the role of ceremonial heads of state in democratic governance and the continuing relevance of centuries-old constitutional conventions in modern political practice.
