Yvette Cooper, UK foreign secretary, said the UK is examining the issue while following discussions between the Taliban and the European Union on returns.
She added that further discussions are also taking place within UK government institutions.
If implemented, such a move would mark a significant shift in current UK policy and could trigger strong opposition from human rights organisations.
The United Nations last month described Afghanistan as a “graveyard of human rights” and raised concerns about “gender apartheid”.
At present, the UK cannot return rejected asylum seekers to Afghanistan as it does not recognise the Taliban administration.
Her remarks come as Sweden has confirmed ongoing talks between Kabul and Brussels on a possible return agreement.
Shabana Mahmood, the UK home secretary, said Britain is closely monitoring developments in other countries, including European partners and their discussions with Afghanistan.
She added: “I am neither confirming nor ruling out this option, and I will not provide further details about internal government discussions at this stage.” Afghans were the largest group arriving in the UK by small boats in the year to June 2025, with around 6,360 arrivals, an 18% increase on the previous year.
Between 2022 and 2024, nearly 29,600 Afghan nationals applied for asylum in the UK.
Acceptance rates have dropped sharply, from 99% in 2023 to 38% in the first half of 2025.
Several European countries are also considering returns, with more than 20 EU states reportedly interested. Germany has deported over 100 Afghan “criminals” since 2024.
Recent reports indicate worsening human rights conditions in Afghanistan, particularly for women and girls.
Detentions, torture and killings of journalists, dismissal of women from public roles and sweeping social restrictions have been highlighted.
Critics warn that returning refugees under such conditions could put their lives at risk.
