That would be good IMHO. Some people will disagree, but the post office going bust, and then nationalised would be a good outcome. It should never have been allowed to be privatised, it’s a national service, a place for providing contact to many different essential national provisions.
True it needed to cut costs, moving into smaller premises does that. Even the partnership with WH Smith’s and village news agents are sensible. But it should fundamentally be a government provision.
And while they are at it nationalise Royal Mail, and properly split Open Reach from BT and nationalise that too.
