Iran has announced that ships must seek permission to use the Strait of Hormuz and has raised the prospect of future charges, which could lead to higher household bills.The Persian Gulf Strait Authority (PGSA), a government agency set up by Tehran during the earlier ceasefire, said vessels would be required to submit requests to pass through the strategic passage at least 48 hours in advance.It also said admin tariffs, including for 'related Iranian insurances', would be waived during the 60-day negotiation period provided for by the interim peace deal to reach a lasting agreement, leaving the way open for fees being levied at a later date.The move came after Donald Trump announced a peace deal between the US and Tehran, ending Iran's stranglehold on the sea route.The blockage of the Strait, which had been a key talking point in negotiations, caused disruption to global oil and gas supplies as 20 per cent of the world's supply travelled through the passage.It also drove up fuel and food prices, with Sir Keir Starmer previously highlighting the 'untold economic damage' caused by the effective closure of the waterway.However, the interim deal to end the nearly four-month war between the US and Iran only secures safe, toll-free passage of the strait for 60 days, pending the outcome of a final settlement on Tehran's disputed nuclear plans.The accord leaves it to Iran and Oman, in conjunction with other Gulf states, to 'define the future administration and maritime services in the Strait of Hormuz'.However, it states this must be 'in line with the applicable international law', which upholds freedom of navigation.Iran's latest move comes despite Mr Trump's previous deal with Tehran and G7 leaders insisting that there should be a 'right of transit passage without restrictions or tolls'.Pictured: Vessels in the Strait of Hormuz.

We didn't meet out of desperation, Iran did,' he wrote. 'They are finished. We'll play out the 60 days. They get no money, not ten cents!'Meanwhile, US Vice President JD Vance restated the country's position at the White House on Thursday, maintaining that international waterways 'should be free of tolls'.'The final negotiations can set the terms of what comes afterwards,’ he added. 'I keep coming back to this fundamental structural point of this negotiation, which is that we have all the cards.'He also said the Strait should 'never used as a chokepoint for the global economy ever again'.Elsewhere, the Prime Minister and his peers welcomed Mr Trump's 'breakthrough' agreement with Iran at a summit in France this week.The G7 group also underlined the need for a 'robust and comprehensive' follow-up accord 'that can bring peace and security for all in the region'.They issued a joint statement, saying: 'We reaffirm that the right of transit passage without restrictions or tolls is the bedrock of international trade.'It backed the UK-French-led effort to enable shipping to pass safely through the strait once hostilities with Iran end, by reassuring commercial operators and verifying the removal of all mines.While Sir Keir has said the UK will play its full part in the defensive mission, he has not yet said when support could arrive.A Foreign Office spokesperson said: 'We congratulate the United States, the Iranian government and all those involved, including Pakistan, Qatar and all other mediators, on this diplomatic breakthrough.'The agreement is a real chance to de-escalate tensions, restore stability, and crucially to reopen the Strait of Hormuz.'Our position has been consistent and will not change. We are clear that toll-free freedom of navigation must now be restored in the Strait of Hormuz in line with international law, to begin easing the severe economic impacts that have been felt for several months – on families here in the UK and around the world. There can be no place for Iranian tolls.'We will continue to work with our partners to ensure the Strait is open to all.'Meanwhile, Israel and Hezbollah agreed to a ceasefire after intensified fighting in Lebanon led planned US-Iran talks in Switzerland to be cancelled on Friday.It comes as the interim deal has enabled Iran to immediately start selling its oil, with the future promise of economic sanctions being lifted.Frozen assets have also been released under the agreement, as well as access to a £227 billion reconstruction fund if they strike a deal on Tehran's nuclear programme.However, the agreement has sparked criticism in Washington, including among some of the US president's Republican allies, who argue the concessions go too far.In addition, Mr Trump abandoned his original promise to destroy Iran's ballistic missiles, arguing it would be 'unfair' if they did not have some.Former president Barack Obama has said it appeared the US was 'worse off' now than before Mr Trump launched the war against Iran in February.He told NBC: 'We've now fought a war, spent billions and billions of dollars, you know, put enormous strain on our military. A lot of people have died.'And it feels like we're back where we were before we started the war, except maybe a little bit worse off.'Mr Obama noted Iran had agreed not to develop nuclear weapons in the 2015 deal his administration struck with Tehran, which was derided and scrapped by Mr Trump in his first term.He said: 'This administration, or a prior version of this administration, pulled out of it, which then caused Iran to develop more nuclear capacity.'
