A source familiar with the Labour leadership selection process said the UK could have a new prime minister on July 17 or 18 if there is only one candidate.

British politics is again in flux as Labour leader Keir Starmer faces an internal rebellion, raising the prospect of a seventh prime minister in ten years and extending policy uncertainty for markets. Two front-runners in early market pricing are Andy Burnham—advocating progressive capitalism, greater state intervention, stronger public services and devolution, long pro-EU but cautious on rejoining (prediction markets ~94% support)—and Wes Stretton, a centrist proposing tax reform (aligning capital gains with income tax) and an explicit pro-EU rejoin stance (prediction markets ~1%). Recent precedent shows leadership moves can be market-moving: Liz Truss’s short-lived fiscal package triggered severe market turbulence and a sharp fall in sterling; Boris Johnson completed Brexit but left after a governance scandal. Structural constraints persist: Brexit’s drag on trade, investment and labour mobility; intense intra-party politics that shorten leaders’ tenures; and concentrated socioeconomic pressures—manufacturing hollowing, ageing population, rising fiscal and public-service burdens, and regional disparities—limit any government’s ability to deliver quick fixes. For asset allocators and macro traders, the immediate implications are elevated political risk and policy uncertainty around fiscal, regulatory and EU-related direction rather than a clear directional break.

Tasnim News Agency, citing insiders, said the United States appears to be circulating messages to divert attention from decisions to grant tax exemptions on sales of oil and its derivatives.
