Incoming UK Prime Minister Andy Burnham is set to be warned that the escalating US-Iran war could overshadow his first week in office, potentially complicating his domestic policy agenda. British officials are expected to brief Burnham that President Donald Trump is serious about his threats to bomb Iranian civilian infrastructure, with the US having struck targets in southern Iran overnight.
According to people familiar with the matter, the assessments will also indicate that the US views its blockade of the Strait of Hormuz as effective leverage against Iran, suggesting a potentially prolonged conflict. Iran, however, is assessed to believe it has the upper hand, having sold approximately $6 billion of oil products during a recent ceasefire and retaining the ability to threaten passage through the vital waterway.
Government officials are privately cautioning that Burnham may be immediately called upon to work with international leaders to de-escalate the Middle East situation. This could divert his focus from planned domestic policy announcements, such as those concerning fossil fuel drilling in the North Sea and public control of the water industry. Keir Starmer, the outgoing Prime Minister, had previously stated that international affairs and domestic policy are intrinsically linked, citing the impact of conflicts on the cost of living.
The intelligence on Iran is compounded by gloomy economic assessments, with Burnham also expected to receive Treasury forecasts warning of a deteriorating economy due to the ongoing conflict. Burnham has yet to announce his foreign secretary but has confirmed that Jonathan Powell will continue as the UK's national security adviser.
