British Passport application issue

[Happy22]

Hello Everyone.
I have a question. I applied for naturalization last year and my application was approved and I was naturalized as a British citizen. All my documents were returned to me except my country of origin passport. Now I want to make an application for a British Passport and the Passport Office said they cannot process my application unless I submit my country of origin passport. However, the Home Office refuses to give me back my country of origin passport and without it I am unable to make a British Passport application. I have wrote to the Home Office explaining to them but to no avail. Has anyone experienced this and if so, how did you make a British Passport application without your country of origin passport?. Any help and advice is appreciated. Thank you.

What reason has HO given for not returning your passport?? They have no authority to hold your foreign passport for no reason.
