Hi

I'm applying for citizenship soon. I believe I will need to supply all passports for the past 5 years? I'm not sure I can locate my old one. My current one is from 2018. Will this be an issue?

Thanks!

As an ILR holder you normally just need to provide your passports covering the residence period.
Where there are gaps it's best to provide alternative documents, such as P60s or Council Tax bills (official documents, not bills or bank statements).
