The Indy and i used to be sister papers, then the i was sold the to the Daily Mail group I think. The Independent went ‘online only’ several years ago.
I hear the Guardian is talking about selling the Observer, home to Azed and Everyman. I don’t doubt that they would survive even if they have to move to the Guardian, though the Guardian doesn’t have a Sunday paper, so they would need another slot during the week or also go online only.
Crosswords are necessarily tied into the newspaper business I suppose.
