I am currently a dual citizen of Nigeria and UK, and recently completed a deed poll to change my name. My first and last name are the same but I've changed my middle name and removed my hyphenated surname. When booking flights I have always only used my first and last name and never had any issues and this will still be the same.

For example, my flight ticket will say 'John Morgan' but

UK passport name is:
John Joseph Smith Morgan

Nigerian name is:
John Adam Morgan

There's no way to change my name on my Nigerian passport without marital change and I'm concerned I'll have issues travelling to Nigeria as they usually ask for both passports at some point.

Any advice is appreciated.
