**Andy Burnham took office as UK Prime Minister on 20 July 2026 after winning the Labour leadership contest unopposed following Keir Starmer’s June resignation amid internal party dissatisfaction.** This marks the seventh premiership change in a decade, driven by Starmer’s declining support among MPs. Burnham, previously Mayor of Greater Manchester, secured overwhelming backing from Labour MPs, unions, and members, pledging to end factionalism, restore stability, and address economic pressures through a long-term plan. Recent developments include his initial cabinet appointments and a Downing Street speech outlining priorities. Key factors influencing his tenure include Labour’s governing majority until the next general election (expected by 2029), public and party confidence in his left-leaning agenda, and potential challenges from economic performance, by-elections, or internal dissent. Scheduled events such as policy announcements and parliamentary sessions in the coming months could shape perceptions of his position.

The departure will be considered to be announced when Andy Burnham, the Government of the United Kingdom, or their authorized representatives publicly and definitively announce that Burnham has ceased or will cease to hold the position of Prime Minister of the United Kingdom. Such an announcement will qualify regardless of when the specified person formally leaves the position. Announcements of the specified person's resignation, removal, or departure through other means all qualify.
Only announcements which are framed as announcing a departure intended to be effective within 18 months of the date of the announcement will qualify (e.g., neither "I will leave office in 2 years," nor "I will not be in office forever," would qualify).
Announcements of temporary leaves of absence, dated suspensions, indefinite suspensions, administrative leaves, or other temporary changes to the specified person's duties in the specified position do not qualify.
The following do not qualify as public and definitive announcements: statements that the specified person is considering or open to departing; conditional statements that the specified person will depart only if certain conditions are met; the announcement of an offer of resignation that requires acceptance and remains pending or has been refused; media reports that the specified person plans to depart; statements made in sarcasm or jest; and statements by persons other than the specified person, the relevant authority governing the specified position, or their respective authorized representatives.
If the specified person holds the specified position on a predefined term with a scheduled end date, only announcements that they will depart the position prior to the scheduled end of their term qualify.
If the specified person formally ceases to hold the specified position before the end of their scheduled term without a qualifying announcement, the market will resolve to "Yes" if a consensus of credible reporting confirms the departure by the specified date, 11:59 PM ET.
The primary resolution sources for this market will be official information from Andy Burnham and the Government of the United Kingdom; however, a consensus of credible reporting may also be used.
