The threat of physical attacks by Iran on people living in the UK has increased “significantly” since 2022, according to a new report by parliament’s intelligence watchdog.

Iran poses a “wide-ranging, persistent and unpredictable threat” to the UK, according to the Intelligence and Security Committee.

It also said Iran’s intelligence services were “willing and able – often through third party agents – to attempt assassination within the UK, and kidnap from the UK”.

The report said there have been 15 murder or kidnap attempts against British citizens or UK-based individuals since the beginning of 2022 and August 2023.

Sky News has approached the Iranian embassy for a comment.

The report authors add: “Whilst Iran’s activity appears to be less strategic and on a smaller scale than Russia and China, Iran poses a wide-ranging threat to UK national security, which should not be underestimated: it is persistent and crucially – unpredictable.”

The committee also says that while the threat is often focused on dissidents and other opponents to the regime, there is also an increased threat to Jewish and Israeli interests in the UK.

The report warns that while Iran has not developed a nuclear weapon, it has taken steps towards that goal.

It found that Iran had been “broadly compliant” with the 2015 Joint Comprehensive Plan of Action (JCPOA), aimed at limiting its nuclear ambitions.

But since Donald Trump withdrew from that deal in 2018, the report said the nuclear threat had increased and Tehran “had the capability to arm in a relatively short period”.

The UK government is also accused of “fire-fighting” rather than developing a real understanding of Iran.

The report says: “The government’s policy on Iran has suffered from a focus on crisis management, driven by concerns over Iran’s nuclear programme, to the exclusion of other issues.

“As one of our expert witnesses told the committee: ‘Strategy is not a word that I think has crossed the lips of policy makers for a while, certainly not in relation to Iran’.”

The committee concluded its evidence-taking in August 2023, the result of two years of work, but the report authors say their conclusions “remain relevant”.

But the report authors questioned whether UK sanctions against individuals would “in practice deliver behavioural change. Or in fact unhelpfully push Iran towards China”.

The committee also said the British government should consider proscribing the Iranian Revolutionary Guards Corps (IRGC), although some argue it would limit the UK’s ability to talk to and influence Iran.

Responding to the report, a UK government spokesperson said: “The government will take action wherever necessary to protect national security, which is a foundation of our plan for change.

“We have already placed Iran on the enhanced tier of the foreign influence registration scheme and introduced further sanctions against individuals and entities linked to Iran, bringing the total number of sanctions to 450.”

British security services say Tehran uses criminal proxies to carry out its work in Britain.

In December, two Romanians were charged after a journalist working for a Persian language media organisation in London was stabbed in the leg. In May, three Iranian men appeared in court charged with assisting Iran’s foreign intelligence service and plotting violence against journalists.

Earlier this year, the UK government said it would require the Iranian state to register everything it does to exert political influence in the UK, because of what it called increasingly aggressive activity.

The first thing you notice when immigration officers stop a possible illegal moped delivery driver is the speed in which the suspect quickly taps on their mobile.

“We’re in their WhatsApp groups – they’ll be telling thousands now that we’re here… so our cover is blown,” the lead immigration officer tells me.

“It’s like a constant game of cat and mouse.”

Twelve Immigration Enforcement officers, part of the Home Office, are joining colleagues from Avon and Somerset Police in a crackdown on road offences and migrants working illegally.

The West of England and Wales has seen the highest number of arrests over the last year for illegal workers outside of London.

“It is a problem… we’re tackling it,” Murad Mohammed, from Immigration Enforcement, says. He covers all the devolved nations.

“This is just one of the operations going on around the country, every day of the week, every month of the year.”

Just outside the Cabot Circus shopping complex, we stop a young Albanian man who arrived in the UK on the back of a truck.

He’s on an expensive and fast-looking e-bike, with a new-looking Just Eat delivery bag.

He says he just uses it for “groceries” – but the officer isn’t buying it. He’s arrested, but then bailed instantly.

We don’t know the specifics of his case, but one officer tells me this suspected offence won’t count against his asylum claim.

Such is the scale of the problem – the backlog, loopholes and the complexity of cases – that trying to keep on top of it feels impossible.

This is one of many raids happening across the UK as part of what the government says is a “blitz” targeting illegal working hotspots.

Angela Eagle, the border security and asylum minister, joins the team for an hour at one of Bristol’s retail parks, scattered with fast food chains and, therefore, delivery bikes.

She says arrests for illegal working are up over the last year by 51% from the year before, to more than 7,000.

“If we find you working, you can lose access to the hotel or the support you have [been] given under false pretences,” she said.

“We are cracking down on that abuse, and we intend to keep doing so.”

There are reports that asylum seekers can rent legitimate delivery-driver accounts within hours of arriving in the country – skipping employment legality checks.

Uber Eats, Deliveroo, and Just Eat all told Sky News they’re continuing to strengthen the technology they use to remove anyone working illegally.

But a new Border Security Bill, working its way through Parliament, could see companies fined £60,000 for each illegal worker discovered, director disqualifications and potential prison sentences of up to five years.

“I had them all in to see me last week and I told them in no uncertain terms that we take a very tough line on this kind of abuse and they’ve got to change their systems so they can drive it out and off their platforms,” the minister tells me.

The gig economy – so prevalent in every city – creates another incentive for those wanting to risk their lives coming to the UK illegally.

More than 20,000 migrants have crossed the English Channel to the UK in 2025 – a record number at this point of the year.

For some of those who arrive, a bike and a phone provide a way to repay debts to gang masters.

There were eight arrests today in Bristol, one or two taken into custody, but it was 12 hours of hard work by a dozen immigration officers and the support of the police.

As two mopeds are pushed onto a low-loader, you can’t help but feel, despite the best intentions, that at the moment, this is a losing battle.

We see the boat from a distance – the orange of the life jackets reflected in the rising sun.

And as we draw closer, we can make out dozens of people crowded on board as it sets off from the shore, from a beach near Dunkirk.

There is no sign of any police activity on the shore, and there are no police vessels in the water.

Instead, the migrants crammed into an inflatable dinghy are being watched by us, on board a private boat, and the looming figure of the Minck, a French search and rescue ship that soon arrives.

The dinghy meanders. It’s not heading towards Britain but rather hugging the coast.

A few of the passengers wave at us cheerfully, but then the boat starts to head back towards the shore.

As it nears a different beach, we see a police vehicle – a dune buggy – heading down to meet it.

Normal practice is for French police officers to slice through the material of any of these small boats that end up back on shore.

Two police officers get out of the buggy and wait. A police helicopter arrives and circles above, performing a tight circle over the heads of the migrants.

The police think they might be about to go back on to the beach; in fact, these passengers know that most of them are staying put.

The boat stops a short distance from the shore and four people jump out. As they wade towards the beach, the boat turns and starts to head back out to sea.

We see the two police officers approach these four men and have a brief conversation.

They don’t appear to check the bags they are carrying and, if they do question them about why they left the boat, it is the most cursory of conversations.

In reality, these people probably don’t speak French but they were almost certainly involved in arranging this crossing, which is against the law. But all four walk away, disappearing into the dunes at the back of the beach.

We follow the boat as it chugs off in the direction of Britain, carrying around 50 people.

The Minck returns to shadowing its progress, but its job is limited to offering help if the boat gets into trouble.

Otherwise, if the engine keeps working, then this flimsy vessel will reach British waters in a few hours’ time.
