Airline statement will reassure Britons abroad anxious about new immigration rules coming into effect next week

British dual nationals may be able to board Ryanair flights in Europe to the UK even if they do not have a current British passport when new immigration rules come into force next week, the airline has said.

The airline is complying with controversial rules being introduced by the Home Office but has said alternative documents that prove a person is a British national may be accepted.

The development will come as relief to many Britons living in Europe panicked by new Home Office rules that require dual nationals to show a British passport or an electronic travel authorisation (ETA) to board a flight to the UK as part of a streamlining of border operations coming into force on 25 February.

Some have had family visits planned while others are worried travel plans may have been scotched by the new rules because children born abroad did not have British passports.
