With the price of oil passing $100 a barrel after the largest one-day spike in six years and the UK’s biggest mortgage lenders raising their rates, the US-Israeli war with Iran is set to have a big impact on Britons’ household finances, with Rachel Reeves warning it is likely to increase inflation.

Indeed, 74% of the public already expect the conflict to have a negative impact on their household’s finances – including 35% who expect it to have a ‘very’ negative impact – relative to only 13% who expect it will make little difference.

While Kemi Badenoch has been amongst those calling on the UK to do more to support the US’s efforts in Iran, opposition to the war among the British public has grown significantly in the last week.

59% of Britons now say they are opposed to the military action that the US has taken against Iran, up ten points since last Monday, though the proportion in favour has remained more steady at 25%, down three points.

Opposition has risen by 17pts among Lib Dem and Green voters, 13pts with Labour voters and 8pts among Conservatives, but is largely unchanged among Reform UK voters.

This leaves Conservatives split 43% to 43% on the US’s actions, while 57% of Reform UK voters support them and 76-87% of Labour, Lib Dem and Green voters oppose them.

Due to the conflict with Iran, Ed Davey has called on the government to call off King Charles’ planned state visit to the US, saying it would be “yet another huge diplomatic coup for President Trump” which “should not be given to someone who repeatedly insults and damages our country”.

The British public tend to agree with the Lib Dem leader, with 46% believing the visit should be cancelled, relative to 36% who believe it should go ahead.

While 67% of Green voters, 63% of Lib Dems and 59% of Labour voters believe the trip should be pulled, 53% of Conservatives and 62% of Reform UK voters want it to go ahead.
