The ongoing conflict in the Middle East, particularly the US-Israeli hostilities with Iran, is poised to escalate the number of small boat arrivals on UK shores, according to Graeme Biggar, the director general of the National Crime Agency (NCA). In his annual threat assessment, Biggar highlighted how geopolitical instability often fuels migration and organised crime, particularly illegal crossings across the Channel.
The Impact of Global Conflict on Migration Trends
Biggar’s assertions come amid a backdrop of rising perilous sea journeys, with small boat arrivals having surged by 13 percent year-on-year in 2025 alone. A total of 45,774 individuals undertook the dangerous crossing to seek asylum in the UK last year. Notably, the majority of these migrants originated from the Horn of Africa, signalling a shift away from previous peaks of asylum seekers from countries like Albania and Vietnam.
While Biggar tempered expectations regarding the scale of new arrivals from Iran, he acknowledged that the ongoing conflict would undoubtedly exacerbate the challenge of unlawful migration. “Migrant demand to reach the UK unlawfully continues to be high, and the conflict in Iran is likely to increase the challenge,” he stated. He cautioned against overstating the numbers but confirmed that some arrivals would likely manifest in small boat crossings.
Organised Immigration Crime: A Growing Concern
Organised immigration crime has become a crucial focus for the NCA, representing a quarter of its operational activities. In an effort to combat the lucrative smuggling operations, NCA officers seized 533 boats and engines last year, disrupting the networks profiting from human trafficking across the Channel. This proactive approach is essential as the rate of small boat crossings remains a pressing issue for British authorities.
As geopolitical tensions rise, the NCA anticipates that migration patterns will evolve, presenting new challenges in their ongoing battle against organised crime. The agency’s strategies will need to adapt to these changing dynamics, particularly as they relate to international legislation and cooperation.
The Dark Side of Drug Trafficking
Alongside the threat of increased immigration, Biggar’s assessment also addressed the alarming rise in drug-related deaths across the UK. Synthetic opioids, particularly nitazenes, have emerged as a significant danger, being linked to a staggering 1,000 deaths in just two and a half years since their introduction to the UK market in June 2023. These potent substances, some 500 times stronger than morphine, are frequently smuggled into the country and found in adulterated heroin or counterfeit pills sold online.
Although there was a slight decline in nitazene-related fatalities in 2025—359 deaths compared to 435 in 2024—Biggar warned that the true figures could be even higher due to inadequate testing capabilities. With half of all homicides, thefts, and robberies in Britain connected to drug use, the urgency for effective countermeasures has never been clearer.
Technological Advancements Fueling Criminal Activity
In his speech delivered at NCA headquarters, Biggar outlined how advancements in technology are reshaping the landscape of crime. Criminals are now employing sophisticated techniques to smuggle drugs and orchestrate complex operations. The NCA has reported that smugglers are using innovative scientific methods to bond drugs with innocuous materials like charcoal and cardboard, complicating detection efforts.
The director general stressed the importance of remaining vigilant against this evolving threat, stating, “While we need to respond to a range of new challenges, we cannot take our eyes off the drug threat. It has always caused a lot of harm, it is evolving fast, and we need to stay on top of it.”
Moving Forward: A Collective Responsibility
In response to the NCA’s findings, security minister Dan Jarvis echoed the urgency of the situation, highlighting the need for a collaborative international effort to dismantle smuggling operations and curb drug trafficking. “The threat from serious and organised crime is rapidly evolving, with criminals collaborating across borders and online to target the British public at scale. As they step up their activity, so must we,” he affirmed.
Why it Matters
The revelations shared by the NCA underscore a critical juncture for the UK, where both immigration and drug-related issues are deeply intertwined with global conflicts and technological advancements. As the landscape grows increasingly complex, the response from law enforcement and policymakers will be pivotal in shaping the future of public safety and national security. The stakes are high, and the need for robust, coordinated action has never been more pressing.
