Britain’s debate about immigration and serious crime is often distorted by merging immigration status, asylum status, nationality, ethnicity, arrest and conviction. These are not equivalent. A foreign national may have lived in Britain for decades; an asylum seeker is not a convicted offender; and ethnicity does not establish immigration status.
The verified evidence nevertheless shows a grave public-safety and safeguarding crisis. An estimated 900,000 people aged 16 and over experienced sexual assault, including attempts, in England and Wales in the year ending March 2025. Police recorded 209,079 sexual offences. Nearly half of recorded rape cases were closed because of evidential difficulties, while cases reaching charge or summons took an average of 434 days.
What the evidence does not provide is a national offending rate for migrants or asylum seekers. The Office for National Statistics said in January 2026 that it did not hold crime breakdowns by asylum-seeker or migrant status. A parliamentary answer likewise confirmed that standard criminal-justice outcome data was not broken down by nationality or immigration status.
The verified 2025 picture
| Measure | Verified figure |
|---|---|
| Adults experiencing sexual assault, including attempts | About 900,000 |
| Police-recorded sexual offences | 209,079 |
| Rape offences closed because of evidential difficulties | 47.5% |
| Rape offences reaching charge or summons by year-end | 2.8% |
| Average time for rape cases reaching charge or summons | 434 days |
The 11% rise in recorded sexual offences was heavily affected by two new intimate-image offences. Excluding those offences, the underlying rise was about 4%. The 2.8% charge-or-summons figure is not a final prosecution rate because some cases remained open.
The wider violence picture did not move uniformly. In the year ending December 2025, police recorded 503 homicides, 6% fewer than a year earlier; 49,151 knife or sharp-instrument offences, down 10%; and 4,753 firearms offences, down 9%. It would therefore be inaccurate to claim that every form of serious violence worsened during 2025.
What the Casey audit established
Baroness Casey’s national audit of group-based child sexual exploitation, published in June 2025, found serious institutional and data failures. It cited more than 100,000 police-recorded child sexual abuse and exploitation offences in 2024, about 17,100 contact offences flagged as child sexual exploitation, and roughly 700 group-based child sexual exploitation offences in a separate 2023 dataset. These figures came from different systems and must not be added together.
Perpetrator ethnicity was recorded in only 31% of relevant Vulnerability Knowledge and Practice Programme reports and 34% of Complex and Organised Child Abuse Dataset reports. The audit found local evidence in areas including Greater Manchester and West Yorkshire indicating disproportionate numbers of Asian men among suspects in group-based exploitation. It said this required further examination.
However, the audit did not establish a national ethnic offending rate and did not measure immigration status. Its findings support two conclusions simultaneously: authorities failed to investigate relevant local patterns with sufficient rigour, and the national evidence cannot justify assigning a general crime rate to an ethnic, religious or immigrant population.
The National Crime Agency’s Operation Beaconport supplied further evidence of investigative failure. By 5 November 2025, it had received 1,273 referred cases from 23 police forces, including 236 rape allegations prioritised for review. These were previously closed cases or allegations under reconsideration, not 1,273 proven crimes or convictions.
What materially changed in 2026
| Development | Position by 13 July 2026 |
|---|---|
| New child-sexual-offence provisions | Enacted in the Crime and Policing Act 2026 |
| Grooming-gangs inquiry | Statutory inquiry established on 13 April 2026 |
| Operation Beaconport funding | £37.7 million for 2026–27 within a £100 million package; announced publicly as about £38 million |
| Mandatory suspect ethnicity and nationality recording | Not fully in force; further legislation was still required |
| Children’s information-sharing duty | Legislated but not commenced, with September 2026 intended |
| Foreign sexual-offender presumption | In force from 2 February 2026 for specified protection decisions |
The statutory inquiry can compel documents and witness evidence, examine institutional failures and consider whether ethnicity, religion or culture affected offending or official responses. It cannot determine criminal or civil liability; criminal allegations are to be referred to Operation Beaconport.
The government’s one-year statement said the work was “far from complete”. That was accurate: the inquiry had not produced substantive findings, the national child identifier remained in development and important data duties were not fully operational.
A separate legal tightening came through the Border Security, Asylum and Immigration Act 2025. From 2 February 2026, specified sexual offences triggering notification requirements were treated as a “particularly serious crime” for certain decisions on Refugee Convention protection. This applies to convicted offenders; it is not evidence of an offending rate among refugees or asylum seekers.
Returns, arrivals and the missing link
The Home Office recorded 39,007 returns in the year ending March 2026, including 9,723 enforced returns and 5,858 foreign-national-offender returns. The latter was the highest figure since 2017 and about 13% higher year on year.[11]
In the same period, 94,000 people claimed asylum, 12% fewer than a year earlier. There were 44,000 detected illegal-entry arrivals, including 39,000 small-boat arrivals. Provisional long-term net migration fell to 171,000 in the year ending December 2025, from a revised 331,000 a year earlier.
None of these totals measures criminality. Arrival route, nationality, visa position and an asylum claim are administrative facts. Foreign nationals comprised about 12% of the prison population in England and Wales in June 2025, but prison stock mixes remand prisoners, sentenced prisoners, offences committed across different years and people with widely differing migration histories.
A grave outlook, but one that must be stated accurately
The outlook remains severe because sexual violence is a high-volume harm, the criminal-justice response is slow, and official reviews have documented failures to pursue evidence, share information and record demographic data consistently. The 2026 response is stronger: there are new offences, a statutory inquiry, a nationally coordinated case review, dedicated funding and tighter consequences for certain convicted foreign sexual offenders.
Yet legislation and announcements are not results. Britain still lacks a national dataset capable of testing claims about offending by immigration or asylum status. That gap can conceal genuine local patterns while also enabling unsupported generalisations. The defensible conclusion is not that immigration has been proved to cause the national sexual-violence crisis. It is that sexual violence is already a profound national emergency, institutional failures were extensive, and the state still lacks the complete evidence needed for precise accountability.
