Will I automatically be sent a BRP card?

I’ve applied for British Citizenship via UKM. Upon approval, will I automatically be sent a BRP card or do they only get issued if you are applying for ancestral, spousal, work, student visas etc? I applied for citizenship while I was in the UK but I’m back in SA at the moment. If I don’t automatically get issued with a BRP card, I’m wondering how I’ll be able to travel back to the UK with a SA passport to attend the ceremony and collect my citizenship certificate. Should I perhaps apply for a 6 month tourist visa to get back to the UK?

There is no BRP card for citizenship. BRP cards are only for immigration/visa applications.

Were you in the uk as a visitor?

Visitor visa is your only option to get back to the uk
