First time British passport application with two other nationalities

[iga]

Good afternoon,
I am appliying first time for my British passport, but I have two other nationalities and the name in one of the passport is slightlhy different as in the country I born we use 2 surnames instead of 1.
- I have born in Peru and when I came to London in 2007, I used my peruvian passport with a spouse visa of european person. My name in my peruvian passport is as per the peruvian laws: Name+Father's Surname+Mother's Surname.
- Whilst living here in London, I applied for my italian nationality and passport. Following the italian law, the name in my italian citizenship certificate and my italian passport is Name+Father's Surname. They have removed the Mother's surname.
- Since then, I have lived and work as an Italian citizenship in London, and got my settled status.
- This year I have applied for a British citizenship and in my British citizenship certificate the name they considered is as per my Italian passport: Name+Father's Surname. I guess because I have applied as an italian person with a second nationality (peruvian)
- Now I am appying for a British passport but they said they cannot give me the document as my peruvian passport has a different name (it has 2 surnames instead of 1, as shown in the italian passport and the british citizenship certificate). They asked me to change the name in my peruvian passport but I cannot do that because the law in Peru consider both surnames.

I have called the HM Passport office and explain that the Home Office has all my records and they know about the differences in my name and they have always accepted it, even when they gave me my British citizenship certificate.
May I please ask your advise?

Can you obtain from the Peruvian authorities a letter, or email, or even a web page print that explains why you can't have your name changed in the Peruvian passport? Perhaps start with the Peruvian embassy/consulate in London? HMPO generally will accept such evidence and won't insist on foreign passport change.
If/when you have obtained such evidence forward this to HMPO - also ask to speak to a senior manager as the advice sometimes given by call agents is inconsistent or even incorrect.
Recommend you review this document: https://www.gov.uk/government/publicati ... -documents
Note that HMPO won't do their own research with other Home Office departments, it's always the applicant who has to provide.

Thank you very much for your answer!
I will review the document and contact the Peruvian Consulate.
Many thanks.

I think you should request to amend these details to the Italian authorities.

I know people with dual nationality - born in Latinamerica and Italian - and both passports have the same name structure (two names + two surnames). Some have never lived in Italy and acquired the citizenship through partners or parents/grandparents.
