Markets are mixed as traders assess Iran talks and the announcement of UK Prime Minister Sir Keir Starmer’s resignation. European stocks and US stock futures slip, suggesting cautious sentiment, while UK assets remain steady, indicating investors’ reactions are not uniform across regions. Oil prices also fall amid the broader risk sentiment, with traders weighing the potential impact of developments in Iran as talks progress. The reports describe the moves as incremental—stocks and futures are wavering rather than sharply reversing—reflecting ongoing uncertainty rather than a single decisive catalyst. Overall, the coverage ties the market movement to two parallel factors: expectations and risks surrounding Iran-related negotiations, and the political change in the UK following Starmer’s resignation announcement. No specific figures or trading ranges are provided in the summaries, and the outlets do not attribute the moves to a particular company or sector. The common thread is that investors are recalibrating exposure as both international diplomacy and UK political leadership uncertainty remain in focus.
