British Prime Minister Keir Starmer has confirmed that the United Kingdom will not participate in the US-proposed blockade of the Strait of Hormuz (the narrow waterway connecting the Persian Gulf to global shipping lanes, through which a significant share of the world's oil and gas passes), saying plainly: "We're not supporting blockade." Starmer framed the decision around economic concerns, warning that a closed strait drives up global energy prices and directly raises household bills for British consumers. The announcement came alongside a broader push by Starmer to deepen UK alignment with EU regulations, which he described as essential given the volatility created by the ongoing Iran conflict and wider global instability.
