Migration Observatory publishes briefing on unauthorised migration to the UK
The Migration Observatory has published a briefing on unauthorised migration to the UK, covering recent trends and developments, and the government’s relevant policies. It looks at how a person can become an unauthorised migrant, the recent significant increase in unauthorised arrivals to the UK (primarily via small boats crossing the English Channel), the position on refused asylum seekers and overstayers, legal returns, (non-)access to jobs, housing and public funds, and regularisation. Between 2018 and September 2024, approximately 175,000 unauthorised arrivals were recorded, with 78% using the small boats route. The majority of these arrivals (94%) subsequently applied for asylum, 70% were granted protection. The report also highlights a decline in returns of unauthorised migrants, though numbers have partially recovered in recent years. Despite strict ‘hostile environment’ policies limiting access to jobs, housing, benefits, and public services for unauthorised migrants, their effectiveness remains unclear. The Observatory notes significant data gaps, including a lack of recent statistics on visa overstayers and regularisation of unauthorised migrants, impeding a comprehensive understanding of the UK's irregular migration landscape.
