THOUSANDS of protesters are expected to call for an end to Britain’s involvement in the Iran war outside RAF Fairford tomorrow amid fears US president Donald Trump will wreck the “fragile” ceasefires.

PM Sir Keir Starmer is being urged to end US use of British military bases, as it is “critical to increase the pressure on the US and provide greater space for diplomacy to successfully end the war.”

Speaking to reporters on Thursday, Sir Keir repeated that he stood by his decision not to drag Britain into the war, which began in late February. It has sparked an international energy crisis due to blockades on the Strait of Hormuz.

Campaign for Nuclear Disarmament (CND) general secretary Sophie Bolt said the protest outside the Gloucestershire base “comes at a critical time.”

“Despite the fragile ceasefire, the US is preparing for further military operations at RAF Fairford, flying in more bombs to the base and carrying out military exercises of its long-range heavy bombers,” she told the Morning Star.

“If Starmer really wants to keep Britain out of this illegal war — as he again claimed on Thursday — he must end Trump’s use of British bases.

“A key military ally pulling out of this illegal war would further isolate Trump. This is critical to increase the pressure on the US and provide greater space for diplomacy to successfully end the war.”

Iran’s foreign minister Abbas Araqchi was set to travel for bilateral peace talks in Pakistan today as Mr Trump announced that a ceasefire between Israel and Lebanon would be extended by three weeks.

A leaked Pentagon internal email, meanwhile, outlined “retaliatory measures” against Nato allies for what it deemed a lack of support for its bombing of Iran – including proposals that the US should reassess its support for Britain’s claim to the Falkland Islands.

Downing Street insisted the sovereignty of the Falkland Islands was “not in question” in the latest sign strains on the US-British so-called special relationship ahead of the King and Queen’s state visit on Monday.

Number 10 also backed Spain’s membership of the “absolutely critical” Nato alliance after the Pentagon email suggested it could be suspended over its refusal to allow bases or airspace to be used to attack Iran.

Stop the War Coalition convener Lindsey German said: “The US and Israel have killed over 3,000 people in Iran and we know US bombers are still operating out of RAF Fairford on a regular basis, despite the ceasefire, because local anti-war activists have been monitoring them.

“Why are our bases still being used to do this? Trump has made it clear — no special relationship with Britain. Starmer’s first response should be to enable peace not war by closing these bases down.”

Momentum co-chair Alex Charilaou added: “Britain should take note from Spain and genuinely condemn the US and Israel’s illegal war on Iran.

“That means withdrawing all ‘defensive’ military support and calling for a permanent ceasefire.

“Diplomacy is the only way to stop this reckless war and the threat of a global economic catastrophe.”

Your Party and the Greens also called for an end to British complicity in the illegal war.

Green Party deputy leader Mothin Ali said: “Keir Starmer has been unable to give guarantees that US planes flying off from Fairford have not been involved in offensive actions and the many war crimes that have been carried out in Iran.

“He needs to come clean about our involvement and stand up to Trump’s reckless and illegal war in reality not just performatively.”

Green Party leader Zack Polanski also called for the government to strip Trump of his Scottish golf courses, as someone who is “enabling a genocide in Gaza, who puts on Truth Social that he intends to wipe out an entire civilisation in Iran.”

A spokesman for Your Party said: “Starmer says it’s not our war, but the truth is his government is complicit in this illegal US-Israeli war of aggression.

“Your Party supports demands for an end to the use of British military bases in this war, with more than 35,000 people supporting our petition.”

Businesses have warned they think food inflation could jump as high as 7 per cent this year, according to Bank of England data.

Bank officials also found that the conflict in the Middle East had “eroded” confidence that the economy will improve later this year.
