United Kingdom in April 2026: the most important developments in politics
In the United Kingdom in April 2026 the most widely reported political event was King Charles III's state visit to the United States, from 27 April. It went ahead after a shooting near a dinner attended by President Donald Trump, and was seen as an attempt to repair relations strained over Iran. On 28 April the king addressed Congress and urged the US to reject isolationism and cooperate with Britain, and Trump called him "fantastic". At the state dinner on 29 April the king remarked that without British help Americans would be speaking French, in reply to Trump's earlier claim that the king was German.
The second story was the row over Peter Mandelson's appointment as ambassador to the US. Olly Robbins, the Foreign Office's top official, left his post on 16 and 17 April over the handling of Mandelson's security vetting, and opposition leaders and some Labour MPs called on Starmer to resign. Starmer refused, ordered a review and a leak inquiry, and apologised for the appointment. Trump said he agreed Mandelson was the wrong pick. On 29 April lawmakers rejected an inquiry into the appointment after Starmer saw off a Labour rebellion.
On the Iran war, Britain hosted talks with 35 to 40 nations on 2 April on reopening the Strait of Hormuz. The US did not take part. Starmer refused to join a US-led blockade of Iranian ports, and on 17 April France and the UK led a summit in Paris on a European mission to secure the strait "as soon as conditions allow". The UK signalled it would not allow the US to use British bases to strike Iranian civilian infrastructure.
The government put plans to hand the Chagos Islands to Mauritius on hold on 10 and 11 April after the US withdrew its support, and a minister said a treaty was now impossible to agree. Parliament also passed a law banning cigarette sales to anyone born after 2008, and an assisted dying bill failed.
