UK Prime Minister Keir Starmer is confronting his most severe political crisis since taking office.
On Thursday, the 14th, internal pressure within the ruling Labour Party escalated: UK Health Secretary Wes Streeting announced his resignation and publicly called for a party leadership contest. Simultaneously, Manchester Mayor Andy Burnham secured a pathway to return to Parliament, widely seen as paving the way for a potential bid for the Labour leadership and even the premiership.
The political turmoil quickly impacted currency markets. Following news of Streeting's resignation during European trading hours on Thursday, the British pound's decline against the US dollar accelerated. During US trading hours, after Burnham announced he would seek to return to Parliament via a by-election, the pound fell further, briefly dropping below 1.3400 to hit its lowest intraday level since April 13, with a daily loss approaching 1%.
Market analysts believe investors are beginning to reprice UK political uncertainty, fearing the Labour Party could descend into a period of frequent leadership changes similar to the chaos seen during the previous Conservative government.
Health Secretary's Sudden Resignation, Publicly Calls for Starmer's Ouster The catalyst for this crisis is the sudden defection of senior Labour figure Streeting.
According to reports from Reuters, The Guardian, and others, Streeting resigned from his post as Health Secretary on Thursday, stating publicly that remaining in the cabinet was "no longer honorable" and calling for a Labour leadership election.
Streeting has long been viewed as a potential candidate for the "post-Starmer era" within the party. He was originally a key ally of Starmer, but tensions between them have rapidly become public. Reports indicate Streeting has criticized Starmer for lacking a clear vision and being unable to lead the party to victory in the next general election.
Notably, Streeting did not immediately formally announce a leadership bid. Analysis suggests a key reason is that he currently lacks sufficient support within the parliamentary party to guarantee a place on the final ballot. Under Labour rules, leadership candidates require significant backing from MPs.
However, his resignation itself is seen as a major signal that the pressure on the party leadership is moving into the public phase.
Media reports indicate several Labour MPs and government officials have recently publicly questioned Starmer's leadership, with some even demanding he set a departure timeline. The party's poor performance in recent local elections has further accelerated the spread of anxiety within its ranks.
"King of the North" Burnham Eyes Parliament Return, Seen as Strongest Challenger More concerning for markets than Streeting may be the latest move by Manchester Mayor Burnham. Opinion polls show he is currently one of the most popular politicians in the UK.
On Thursday, Labour MP Josh Simons unexpectedly announced his resignation from his parliamentary seat, clearing the path for Burnham to contest the by-election and return to Parliament.
Since the leader of the UK Labour Party must typically be a Member of Parliament (MP), Burnham, despite his high public popularity, has lacked the formal qualification to challenge Starmer. Now, that institutional barrier is being removed.
Media reports state Burnham is now widely regarded as one of the most formidable potential challengers to Starmer.
Burnham, born in the suburbs of Liverpool, worked in journalism and for a trade union before becoming an advisor to Tony Blair's government in the late 1990s. He was elected as an MP in 2001, later rising to cabinet positions, including serving as Health Secretary under Gordon Brown. After unsuccessful bids for the Labour leadership in 2010 and 2015, Burnham resigned as an MP in 2017 to become the first Mayor of Greater Manchester.
Leading Manchester, Burnham has in recent years built substantial support in northern England through public transport reforms, local governance, and a policy stance leaning more towards the "soft left," earning him the media nickname "King of the North" within the Labour Party.
Multiple polls indicate Burnham's approval ratings among the general electorate and Labour grassroots are even higher than Starmer's. In some surveys, Labour supporters prefer Burnham over Starmer to be Prime Minister.
However, Burnham is currently maintaining a relatively cautious stance. He has not publicly announced a challenge to Starmer, instead stating he wishes to "give the government space for stability." But markets widely perceive his move to return to Parliament as carrying significant political signaling in itself.
Why Has Starmer Suddenly Found Himself in a "Governing Crisis"? Just over a year ago, Starmer led Labour to end the Conservatives' long period in government and was seen as "Mr. Stability" in British politics.
Now, his support has significantly eroded.
Analysis suggests core reasons for Starmer's crisis include:
A sluggish UK economic recovery, with continued public dissatisfaction over the cost of living; Failure to deliver on some reform promises since taking power; Policies like cuts to winter fuel payments sparking backlash from the party base; Poor Labour performance in recent local elections; The rapid rise of right-wing populist forces like Reform UK.
More critically, concerns are growing within the Labour Party that under Starmer's continued leadership, it may not be able to retain power in the next general election.
This is pushing discussions about an "early leadership change" from behind the scenes into the open.
Despite this, Starmer has so far refused to resign. On Thursday, he stated he would "fight to the end" and warned that an internal leadership battle could plunge the UK back into political chaos.
If the UK "Changes Prime Minister," What Are Financial Markets Most Worried About? For financial markets, what truly unsettles investors is not just "who becomes Prime Minister," but whether the UK will re-enter a period of sustained political infighting.
After the frequent leadership changes during the Johnson, Truss, and Sunak eras, markets had hoped the Labour government would bring long-term stability. Now, with internal Labour strife heating up again, it suggests the UK's political risk premium may be returning.
Institutional analysis suggests that if Labour initiates a leadership contest:
Sterling could face further short-term pressure; UK government bond (gilt) volatility may increase; Investors will reassess the UK's fiscal discipline and economic reform path.
However, most analysts also note that regardless of whether Streeting or Burnham eventually succeeds, the broad direction of UK macroeconomic policy is unlikely to see a dramatic "Truss-style" shift.
The real risk is more likely to stem from prolonged political uncertainty itself.
