(Sharecast News) - US vice‑president JD Vance left Islamabad on Sunday after more than 21 hours of talks failed to produce an agreement with Iran, according to the Guardian.

Vance said Tehran had declined to accept US terms, including commitments not to pursue nuclear weapons, and described the outcome as a setback "more for Iran than for the United States".

He said he had spoken with Donald Trump several times during the negotiations, adding that Iran's nuclear programme remained one of the key points of disagreement.

More than 500 people were arrested during a mass demonstration in Trafalgar Square opposing the proscription of Palestine Action, after the High Court ruled the group's ban unlawful.

The Guardian reported that protesters held signs reading "I oppose genocide. I support Palestine Action", with hundreds sitting on the ground or in camping chairs.

The Metropolitan Police said 523 people had been arrested by midnight, with ages ranging from 18 to 87.

UK wholesalers have warned chancellor Rachel Reeves that soaring fuel prices were threatening the stability of the food and drink supply chain, as the war in Iran continues to disrupt global markets.

The sector, which supplies retailers and public services, said rising petrol and diesel costs were "causing major issues" and risked undermining long‑term sustainability.

In a letter seen by The Times, wholesalers said further increases would force them to pass on costs to local businesses, driving up prices and adding to food inflation.

North Yorkshire‑based sausage maker Heck was said to be exploring a move into lab‑grown meat as it looks to protect the business from global disruption, according to the Times.

Managing director Jamie Keeble said the company was assessing how it could bring cultivated products to market in the coming years, describing the technology as a sustainable safeguard against events such as livestock disease outbreaks.

Heck previously held talks with Ivy Farm Technologies in 2021 but did not proceed at the time. Keeble said discussions with the Oxfordshire biotech firm had since resumed.

UK officials are examining alternatives to Sir Keir Starmer's agreement with Mauritius over the future of the Chagos Islands, according to the Independent, after the Foreign Office paused ratification amid US opposition.

One option under consideration would allow Chagossians to resettle the islands - a move that would mark a significant reversal for the prime minister, who had pursued a deal handing sovereignty to Mauritius alongside a financial package.

Legal representatives for the Chagossians have asked the United Nations to intervene, arguing the agreement amounts to "crimes against humanity".

Hungarian voters go to the polls on Sunday with prime minister Viktor Orban facing his toughest electoral test in 16 years as opinion polls suggest his Fidesz party could lose power to the centre‑right, pro‑EU Tisza party led by Peter Magyar, a former ally.

US vice‑president JD Vance briefly joined Orban on the campaign trail, praising him as a defender of "western civilisation", according to the Independent.

Orban, a close ally of Vladimir Putin, has drawn criticism across Europe for his stance on the war in Ukraine and his comments dismissing Russian drone incursions into NATO airspace.
