I am only speculating but here goes…
If the Instagram post alluding to a big story hitting the papers either this Sunday or next is true, then I have 3 theories.
Theory 1 - This is the dossier a journalist has been compiling for a while. Was awaiting legal sign offs before being able to have it published (as per festival of bins). We were told the release of this would coincide with with bankruptcy hearing which is about 3 weeks away now (to maximise damage). A Journo perhaps that works with Reach PLC?!
Theory 2 - Carl is the source feeding tidbits to the papers about their recent fallouts. He could be ready to drop her and tell all
Theory 3 - Peter has had enough of her shit and is ready to bring her down. Hence the meeting with Claire
I really hope that whatever it is happens
