So Mum went to register the death today.
Only to be told by Uncle D that it was nothing to do with her, that she wasn't to interfer and he would make all the arrangements and to pass over Nan's finances immediately. Oh and the funeral would be at some point in September as "we all have holidays booked".

Mother went hysterical, flew back to Grotty this afternoon. I'm here to pick up the pieces as always. She took my house and car keys with her.
That's a bit of a nuisance really.
