Three Iranian men have been charged with offences under the National Security Act in the UK, police have said.

The trio have been charged with engaging in conduct likely to assist a foreign intelligence service between 14 August 2024 and 16 February 2025, following an investigation by counter-terror police.

The Metropolitan Police said the three men are Mostafa Sepahvand, 39, Farhad Javadi Manesh, 44, and Shapoor Qalehali Khani Noori, 55.

The foreign state to which the charges relate is Iran, police said.

All three men will appear at Westminster Magistrates Court on Saturday, the force added.

Sepahvand, of St John’s Wood, London, has also been charged with “surveillance, reconnaissance and open-source research” with the intention of “committing serious violence against a person in the UK”, according to a police statement.

Meanwhile, Manesh, of Kensal Rise, London, and Noori, of Ealing, London, have also been charged with “engaging in conduct, namely surveillance and reconnaissance, with the intention that acts, namely serious violence against a person in the UK, would be committed by others”.

Commander Dominic Murphy, from the Metropolitan Police’s Counter Terrorism Command, described the charges as “extremely serious”.

“Since the men were arrested two weeks ago, detectives have been working around the clock and we have worked closely with colleagues in the Crown Prosecution Service to reach this point,” he said.

“Now that these men have been charged, I would urge people not to speculate about this case, so that the criminal justice process can run its course.”

A fourth Iranian national aged 31 who was arrested was released with no further action on Thursday.

In a separate unrelated probe, counter-terror officers arrested five Iranian men, aged between 29 and 46, during raids across various locations in Greater Manchester, London, and Swindon earlier this month.

Last October, MI5 director general Ken McCallum said the UK intelligence agency had responded to 20 “potentially lethal” Iran-backed plots since 2022, warning of the risk of an “increase or broadening of Iranian state aggression in the UK”.

NASA’s Europa Clipper Spacecraft took a haunting infrared portrait of Mars flyby during its journey to Jupiter’s icy moon Europa on March 1, 2025. The spacecraft used the planet’s gravity to change the speed and orbit for the next phase of its long interplanetary journey, reaching 550 miles above the Martian surface. This encounter allowed the team to test E-THEMIS, an instrument known as a thermal imager which is designed to study the surface of Europa fr potential life signs.

Mars Flyby Serves as Key Instrument Calibration

According to report by NASA , Mars flyby has been used as a critical instrument calibration moment for Europa Clipper. E-THEMIS, at its 18-minute duration, took 1000 greyscale snapshots of infrared, started reaching Earth on May 5. On comparison of this recent dataset with thermal maps from the Mars Odyssey Orbiter for verifying the accuracy of the imager. Since Odessey was observing Mars from 2012, it provided a rich thermal standard to compare.

Infrared Imaging to Detect Geologic Activity on Europa

Phil Christensen investigated the data and made sure the images taken by E-THEMIS match with the Thermal data of Mars mapped twenty years ago. E-THEMIS detects infrared light and enables scientists to map the variation of the temperature across the planetary surface.
When Clipper reaches Europa, the instrument uses this potential to locate the hotspots, connected to the recent geologic activity under the icy crust of Jupiter’s moon. This signals the search for extraterrestrial life.

Tracing Europa’s Subsurface Ocean with Heat Signatures

E-THEMIS imaging is helpful to find the hidden ocean of Europa, which is situated closest to the surface. The ridges and fractures of the icy moon are the result of the oceanic forces. The warm temperature in such areas could signal previous eruptions. Further, it can also lead to areas where the middle surface ocean moves upward.

Future Flyby Mission Plans

For the first time in space, this Mars flyby tested the radar instrument, too. The test went smoothly as per the data, however, scientists are still analysing the results. Another Clipper will do an Earth flyby in 2026, before landing at Jupiter in April 2030 to explore the habitat potential.

Quintessentially, the luxury concierge service founded by the Queen’s nephew, is in talks to find a buyer months after it warned of “material uncertainty” over its future.

Sky News has learned that the company, which was set up by Sir Ben Elliot and his business partners in 1999, is working with advisers on a process aimed at finding a new owner or investors.

City sources said this weekend that Quintessentially was already in discussions with prospective buyers and was anticipating receipt of a number of firm offers.

Sir Ben, the former Conservative Party co-chairman under Boris Johnson, owns a significant minority stake in the company.

The Quintessentially group operates a number of businesses, although its core activity remains the provision of lifestyle support to high net worth individuals including celebrities, royalty, and leading businesspeople.

It also counts major companies among its clients and offers services such as organising private jet flights and performances by top musicians.

The sale process is being overseen by a firm called Beyond, although further details, including the price that the business might fetch, were unclear on Saturday.

One insider said parties who had been contacted by Beyond were being offered the option to buy a controlling interest in Quintessentially.

This could be implemented through a combination of the repayment of outstanding loans, an injection of new funding into the business, and the purchase of existing shareholders’ interests, they added.

Quintessentially’s founders, including Sir Ben, are thought to be keen to retain an equity interest in the company after any deal.

In January 2022, newspaper reports suggested that Quintessentially had been put up for sale with a valuation of £140m.

Deloitte, the accountancy firm, was charged with finding a buyer at the time but a transaction failed to materialise.

Sir Ben, who was knighted in Mr Johnson’s resignation honours list, turned to one of Quintessentially’s shareholders for financial support during the pandemic.

World Fuel Services, an energy and aviation services company, is owed £15.5m as well as £3.5m in accrued interest, according to one person close to the process.

The loan is said to include a warrant to convert it into equity upon repayment.

Quintessentially does not disclose the number or identities of many of its clients, although it said in annual accounts filed at Companies House in January that it had increased turnover to £29.6m in the year to 30 April 2024.

The accounts suggested the company was seeing growth in demand from clients internationally.

“During the last year, we have not only renewed important corporate contracts like Mastercard, but have also expanded by adding new corporate clients like Swiss4 in the UK, R360 in India, and Visa in the Middle East and South America,” they said.

In its experiences and events division, it won a contract to work with the Red Sea Film Festival and to provide corporate concierge services to the Saudi Premier League.

It added that Allianz, the German insurer, BMW, and South African lender Standard Bank were among other clients with which it had signed contracts.

The accounts included the warning of a “risk that the pace and level at which business returns could be materially less than forecast, requiring the group and company to obtain external funding which may not be forthcoming and therefore this creates material uncertainty that may cast ultimately cast doubt about the … ability to continue as a going concern”.

This weekend, a Quintessentially spokesman declined to comment on the sale process.
