At 76, King Charles III is grappling with a critical phase in his cancer battle, diagnosed in February 2024 following a procedure for benign prostate enlargement. The illness, which worsened throughout 2025, has sharply curtailed his public engagements, dropping from over 200 in 2024 to fewer than 50 this year. Buckingham Palace has not revealed the specific type of cancer, but the lack of remission and intensified medical care point to a concerning prognosis. As a result, the British monarchy is hastening succession preparations, with Prince William, 42, and Kate Middleton, also 42, stepping into central roles. Charles, who ascended the throne in September 2022 after Queen Elizabeth II’s death, now faces a reign of just over two years clouded by uncertainty, prompting the Crown to reorganize and ensure continuity amid health challenges and institutional pressures.
William has emerged as the king’s primary stand-in, taking on about 80% of his representational duties in 2025. In 2024, he attended over 150 events—a 30% increase from the previous year—including the Notre-Dame Cathedral reopening in Paris in December. He has also delved into administrative and charitable roles, managing royal estates and raising £20 million for mental health initiatives. Kate, meanwhile, is battling her own cancer, diagnosed in January 2024 after abdominal surgery, which reduced her engagements from 120 in 2023 to 40 last year. Despite this, she plans 20 events in 2025, remaining vital to the succession plan and reinforcing her training alongside William to lead the United Kingdom and its 56 Commonwealth nations.
Charles’s health has significantly altered royal dynamics, fueling speculation about a possible abdication, though no official statement has been issued. As the king prioritizes treatment, the heir apparent couple undergoes intensive training in royal protocols, foreign policy, and monarchy modernization. This looming transition positions William and Kate as key figures in preserving the Crown’s stability, especially as the institution faces questions about its relevance and economic challenges. The future of the British monarchy, which contributes £1.8 billion annually to the UK economy, now hinges on the couple’s ability to take charge in a time of crisis.

Intensive training marks William and Kate’s rise
Prince William has become the monarchy’s frontline figure in 2025, shouldering the bulk of responsibilities once held by Charles III. With over 150 events in 2024 and 80% of the king’s duties this year, he has engaged in diplomacy, estate management, and philanthropy, raising £50 million in donations last year. His efforts included 10 international trips in 2025 and over 20 meetings with foreign policy experts, signaling robust preparation for the throne. William’s popularity, reaching 75% among Britons, reflects his ability to align the monarchy with contemporary demands like sustainability and mental health, areas that benefited 5 million people in 2024.
Kate Middleton, despite the toll of her cancer treatment, remains an active player in the transition. After a 70% drop in engagements in 2024—from 120 to 40 events—she plans a gradual return with 60 commitments in 2025, focusing on early childhood education, a cause that has reached 2 million children. Her resilience amid personal adversity has boosted her public approval, up 10% since 2023 to match William’s 75%. Together, the couple works to modernize the institution, a pressing need as 40% of Britons question the monarchy’s £100 million annual cost in 2024 polls, despite its £1.8 billion economic impact, including £500 million from tourism.
The preparation of William and Kate extends beyond ceremonial roles, encompassing a strategic agenda to bolster the Crown’s relevance. In 2024, their charitable initiatives made a significant mark, with William’s £20 million for mental health and Kate’s projects expanding educational access standing out. Their 70% approval rating as “relevant” contrasts with Charles’s 55%, whose popularity fell from 65% in 2023 to 50% in 2025 due to his declining health. This gap underscores the perception that William and Kate are ready to lead a monarchy more attuned to 21st-century challenges.
Charles III’s health reshapes royal roles
Diagnosed with cancer in February 2024, Charles III has seen his ability to fulfill royal duties plummet in 2025. The king, who managed over 200 engagements in 2024, participated in fewer than 50 this year, a steep decline reflecting the focus on medical treatment. The illness surfaced after a procedure for benign prostate enlargement, but its progression over the months has laid bare the fragility of his reign, which began in September 2022. As Charles steps back from public life, the monarchy shifts its priorities, with William taking on 80% of the king’s tasks and Kate contributing within her health constraints.
The king’s international presence has also dwindled. In 2023, he undertook 25 overseas trips, a number that fell to fewer than 10 in 2024, while William ramped up his global role with 10 trips in 2025. Kate, despite attending only 15 events in 2024, plans 20 engagements this year, emphasizing early childhood education. The couple’s health struggles have shaped public perception: their approval rose 10% since 2023 to 75%, while Charles’s dropped to 50%. This disparity highlights the ongoing transition and the trust placed in the heirs to maintain institutional stability.
The health crisis has also hastened Prince George’s introduction to royal duties. At 11, he attended five public events in 2024, an initial step toward preparing him as a future king. The line of succession is solidifying: William will take the throne upon Charles’s abdication or death, with Kate as queen consort, followed by George, Charlotte, and Louis. The royal family navigates a period of adaptation, with Charles and Kate’s health testing the monarchy’s resilience amid historic changes.
Timeline of British succession
The British monarchy’s history provides context for the current transition. Key events have shaped the Crown over the years, and Charles III’s reign may become one of the shortest since the 20th century. Here are the major milestones:
- 1936: Edward VIII abdicates to marry Wallis Simpson, succeeded by George VI.
- 1952: George VI’s death elevates Elizabeth II to the throne at 25, reigning for 70 years.
- 2022: Elizabeth II’s passing crowns Charles III at 73, the oldest monarch to ascend.
Charles’s reign, now just over two years, faces potential interruption due to his health, accelerating William’s rise. Unlike his mother, who ruled for seven decades, Charles may leave a briefer legacy, akin to Edward VIII, whose reign lasted less than a year. William and Kate’s preparation reflects the urgency of ensuring a smooth power transfer in this uncertain landscape.
Challenges and modernization amid the transition
The British monarchy faces mounting pressures as it prepares for succession. Of the 56 Commonwealth nations, 14 still recognize the monarch as head of state, but republicanism is gaining traction. Barbados severed ties in 2021, 10 others plan referendums by 2030, and six debate the issue in 2025. The Crown’s £100 million annual cost draws scrutiny, with 40% of Britons questioning its value in 2024, despite its £1.8 billion economic boost, including £500 million from tourism.
William and Kate counter these challenges with a modernization agenda. In 2024, their initiatives reached 5 million beneficiaries, with William focusing on mental health and sustainability and Kate on early childhood education. Their 75% approval rating outpaces Charles’s 50% and the royal average of 55%, a critical asset for maintaining relevance. Their ability to generate £50 million in donations last year underscores the monarchy’s positive impact, while their 20% higher approval could help preserve Commonwealth ties amid uncertainty.
The impending transition tests William and Kate’s ability to balance tradition and innovation. As Charles undergoes intensive care, the couple takes the reins, with William’s 10 international trips and Kate’s 20 planned engagements in 2025 signaling a handover in progress. The Crown’s future, influencing 2.5 billion Commonwealth citizens, now rests on their resilience and vision to lead the monarchy into a new era.
