The UK could be weeks away from thinking about having to ration jet fuel and possibly diesel, an industry source has said. The unnamed source said it seemed as if the Labour Government has no plan as there was "nothing more concrete" from ministers on how the UK would handle fuel shortages.

They told the Daily Mail: "You don't want to leave it too late. People need to plan." Their comments came as Prime Minister Sir Keir Starmer chaired another meeting to discuss the impact on households and the economy of soaring energy costs, this time with members of the Cobra crisis committee.

Meanwhile, US President Donald Trump took another swipe at the UK and Europe, insisting they should build up some "delayed courage" and get their own oil.

Mr Trump wrote on Truth Social: "All of those countries that can't get jet fuel because of the Strait of Hormuz, like the United Kingdom, which refused to get involved in the decapitation of Iran, I have a suggestion for you: Number 1, buy from the US, we have plenty, and Number 2, build up some delayed courage, go to the Strait, and just TAKE IT.

"You'll have to start learning how to fight for yourself, the USA won't be there to help you anymore, just like you weren't there for us. Iran has been, essentially, decimated. The hard part is done. Go get your own oil!"

Industry body Airlines UK has refuted Mr Trump's claim the country can't get jet fuel.

US Secretary of War Pete Hegseth joined in, making dismissive comments about the Royal Navy and echoing Mr Trump's by suggesting countries should "step up" and re-open the Strait of Hormuz, which Tehran closed in response to the US-Israeli attack on Iran.

A number of countries have either cut taxes on petrol or capped prices at the pumps to help hard-pressed motorists. Britain's Government has yet to outline its response.

However, the Prime Minister is due to speak at a press conference on Wednesday after vowing to "protect the British people at home and abroad".

It is thought Sir Keir's Downing Street press conference will cover both the conflict and Government support for households as rising prices bite.

Since fighting began in Iran, oil prices have soared in response to Tehran's block on tankers passing through the Strait of Hormuz. Families with a 55-litre diesel car face paying more than £100 at the pump for the first time since December 2022.

Sir Keir said: "I know the public are concerned about the conflict in Iran and what it means for them and their families.

"I want to reassure them that they have a Government on their side, working with allies on de-escalation and bearing down on the cost of living.

"Today, millions of people up and down the country will see energy bills go down by £117, wages go up for the lowest paid and more support will be available for people who need it most - because of the decisions this Government has taken.

"But we must go further to bear down on costs, and that means pushing for de-escalation in the Middle East and a re-opening of the Strait of Hormuz. That is the best way we can bring down the cost of living for families and that is my focus."

The price most households pay for energy under regulator Ofgem's price cap will fall by 7%, or £117 a year, to £1,641 from Wednesday.

Energy analyst Cornwall Insight said its prediction for the watchdog's price cap from July to September now stands at £1,929 for a typical dual fuel household - an increase of £288 or 18% on April's cap.

RAC figures on Tuesday showed average diesel prices at UK forecourts were 182.8p per litre, up 40p since the start of the conflict, which brought the cost of filling up a 55-litre family car to £100.52.

The average cost of petrol is 152.8p per litre, an increase of 20p since the war began.
