UK Data Ranks Nigeria 10th In Africa For Illegal Entries
Five hundred and thirty one Nigerians were detected entering the United Kingdom through illegal routes between the first quarter of 2018 and the first quarter of 2026, according to official immigration figures released by the UK Home Office, a body of data that places Nigeria tenth among African nationalities recorded on the country’s illegal entry ledger.
The figures, contained in the Home Office’s immigration system statistics data tables on illegal entry routes published in March 2026, offer a rare granular look at how Nigerians move outside authorised channels, and how rarely they succeed once inside the asylum system. The dataset captures only detected arrivals, meaning the true scale of undetected entries remains unknown.
What sets Nigeria apart is the method. While the global picture is dominated by the perilous Channel crossing, with small boats accounting for 197,074 of the 269,739 total detections, more than 73 per cent, Nigerians overwhelmingly arrive by air. Of the 531 detections, 297 landed at UK airports without valid travel documents, 175 crossed the Channel by small boat, 46 were caught inside the country, and 13 at border ports of entry. That air-dominant profile marks Nigeria out sharply from the wider trend.
The year by year breakdown shows detections of Nigerians climbing from 36 in 2018 to a peak of 92 in 2022, the same year global illegal entries hit a record 54,574. Numbers then eased to 57 in 2023, rose slightly to 61 in 2024, fell to 46 in 2025, and stood at 11 in the first quarter of 2026. Across the full period, 407 of those detected were male. The largest cluster, 259 people, fell between the ages of 25 and 39, while 121 were aged 40 and above and 62 were minors under 17.
The asylum outcomes are stark. Of the 163 Nigerians who arrived by small boat and lodged asylum claims, only 18 received formal protection at the initial decision, a grant rate of 16.8 per cent. That sits far below the global small boat protection rate of 59.6 per cent, placing Nigerians among the nationalities least likely to succeed through the Channel route. Of 107 decided claims, 89 were refused, 24 were withdrawn, and eight drew administrative outcomes.
Concerns beyond immigration also surface in the records. The Home Office disclosed that of 167 Nigerians recorded arriving by small boat between 2018 and December 2025, 59 were referred to the National Referral Mechanism, the government’s system for identifying potential victims of modern slavery and human trafficking. Referrals peaked at 19 in 2024, the highest annual figure on record.
Across the continent, Eritrea led with 27,368 detections, followed by Sudan at 20,508, Somalia at 6,270 and Ethiopia at 5,105. Nigeria’s 531 ranked tenth, ahead of Morocco, Guinea, Sierra Leone and Tanzania. Globally, Iran topped the table with 45,442 detections, and Nigeria ranked 29th.
The broader crossing crisis has driven sustained action in Westminster. UK figures show Channel arrivals climbing from 299 in 2018 to a peak of 45,774 in 2022, easing to 29,437 in 2023, then rebounding to 41,472 in 2025. In response, Parliament passed the Illegal Migration Act in 2023 and the Border Security, Asylum and Immigration Act in 2025, while committing £662m to France between 2026/27 and 2028/29 to disrupt crossings.
The pressure has reshaped bilateral relations. During President Bola Tinubu’s state visit to the UK in March 2026, both governments signed a removals agreement under which Nigeria recognised UK identification letters for the first time, clearing a long standing administrative hurdle to deporting Nigerians with no legal right to remain. Announcing the deal, the UK described Nigeria as its largest African visa market. According to UK government figures, removals and deportations have reached nearly 60,000 since the July 2024 election.
