OCI Application - Silly Question

I'm completing my OCI application online using the "Online OCI Services" website at passport.gov.in.

I've got a quick question regarding the 'Passport Information' section. The passport details required there is my current British passport, yes? Not the cancelled Indian passport details? I wish they would put some sort of helpful information for their forms

Thanks in advance.

Follow-up question - Place Of Issue for the passport. British Passports don't have a 'Place Of Issue'. So what do I fill in?

Thanks
