Thought of clearing confusion on BRP vs Passport debate while sending documents for provisional licence.
Almost all friends (& the gentleman at postoffice) advised me to send passport to DVLA. Else, a rejection of provisional is imminent.
However, I just sent BRP card (i.e. no passport) via special delivery to DVLA office. I got my provisional licence a few days back.

Based on my experience, I will safely extend the argument that 'current passport' too suffice. No need for sending your all old passports.
In summary, BRP is OK, no need of passport at same time.
