London-born woman left stranded in Spain after UK border rule change

A London-born woman has been left stranded in Spain after being denied re-entry to the UK due to new border rules.

Denied boarding at the gate: Natasha’s story

Natasha Cochrane De La Rosa, a 26-year-old woman born and raised in Islington, North London, was due to fly back to the UK on Monday, April 6 after a short holiday in Amsterdam with her friends. While she was able to go through check-in, security and passport control, she was denied boarding at the gate, in what she called an “utter surprise.”

On February 25, 2026, the Home Office introduced a new restriction stating dual nationals are no longer able to enter the UK using a foreign passport alone; they must now present either a British or Irish passport, or a digital certificate of entitlement.

Natasha has a British father and a Spanish mother, but the circumstances of her birth have complicated the bureaucracy for her; as her parents were unmarried when she was born in 1999, her father was not able to pass on his citizenship. Natasha said this has left her in a “grey area.”

UK government offers two options

In order to get home, Natasha must either pay £589 (just over €670) for a digital certificate of entitlement, or apply for a British passport, which could take up to six weeks and carries a risk of denial due to the circumstances of her birth. Additionally, in order to apply for the passport, she must prove her mother had free movement rights across the EU when she was born, but Natasha says she has never received paperwork for this.

“[The airline] called immigration on the phone basically saying these new laws had come in. I was showing my birth certificate, my national insurance, my P45, my dad’s birth certificate and was still denied boarding as I had not got the right documentation.”

‘My whole life is in the UK’

Natasha also expressed fears that she might lose her job due to the ordeal. She is a client success manager who lives in Haringey, North London.

“I was born in Islington, I have paid taxes, I have voted. I am a dual national. I do have British nationality but the government is saying none that I have lived for 26 years matters anymore.”

“I have a career, family and friends in the UK. My whole life is in the UK,” she told BBC London.

Stranded in Sevilla

Natasha is currently staying in Spain with a family friend. When she was unable to board the flight back to London, she booked another flight from Amsterdam to Sevilla.

“Luckily, I am privileged enough to have a haven essentially, but if I didn’t have any ties to my country, didn’t speak the language or have anywhere to stay, I would have been left homeless in the Netherlands,” Natasha said. “I feel the government has failed and they have a responsibility to dual nationals and the population of the UK that such dramatic and important law changes are effectively communicated.”

She said that she had previously travelled back and forth from the UK on her Spanish passport without issue. She also stated that many people have commented on her social media, saying they would have been in the same situation if they had not found out what had happened to her.

“Whilst I do take responsibility for not having checked, why would I check something that for 26 years of my life I’ve never had to do?”

Spokesperson for the Home Office: There has been a ‘substantive’ communications campaign

A Home Office spokesperson said: “Since 25 February 2026, all dual British citizens need to present either a valid British passport or certificate of entitlement when travelling to the UK.”

They also reiterated the UK government’s communication of the changes: “Public information advising dual nationals to carry the correct documentation has been available since October 2024 and a substantive communications campaign about the introduction of ETA has been running since 2023. This requirement applies to all British citizens regardless of other nationality and is the same approach taken by other countries, including the United States, Canada and Australia.”
