Travelling Post Citizenship Ceremony on Foreign Passport

[Dzhanan]

Hi everyone!
I hope someone can help. My husband and I became british by naturalisation couple of weeks ago but haven’t had a chance to apply for the British passport yet. My question is - my husband is Turkish, after the ceremony we sent his BRP back to Home Office; I’ve completely forgotten about that and booked a holiday to Turkey. We’ll not have enough time to apply for a passport before we travel - will he be alright to travel with his Turkish passport and enter the UK without his BRP? We have the original Naturalisation Certificates - surely these should be an evidence of us being British and exempt from immigration controls etc. I’d assume Border Police will be able to see on the system we are British. Any advice much appreciated! If not I’ll need to cancel the booking...
P.s : I’m an EU national so no issues for my travelling...

Unfortunately you can not travel in this situation without a British Passport. You did the right thing to return the ILR BRP as its the law. Your ILR BRP becomes invalid after you become British i.e. attend the ceremony. You will not be able to board a flight from Turkey to UK in the first place with only Naturalisation certificate in hand and no British passport/valid ILR. You need a British Passport now to travel and come back to UK.

The main problem that your husband may face is not being allowed to board the flight. He will need to demonstrate his right to enter the UK to the airline staff, who will be looking for a stamp in his passport, a BRP or a passport that will allow him to enter the UK. The airline staff will have no ability to check the authenticity of the naturalisation certificate. Remember that Stupid face huge fines if they fly somebody who has no right to enter the UK and they will be unwilling to take the risk.

If he can get to the UK border, he should be allowed to enter the UK, but there may be a delay at the airport while his details are being checked.
