Only a guess ...
1. The court case goes against BT and they have to pay £1bn+.
2. Divi cancelled to fill some of the gap.
3. Share price drops maybe 10%.
4. Draghi screws as no div to find his debt and his holding has halved in value.
5. DT offer Draghi some cash, perhaps not enough for his holding.
6. DT takeover BT.
Caught a bit of this today - dear Lord, Crozier is a charlatan. I'm the context of the post office, he looks awful. Poor recollection, no accountability. In the context of everywhere else he's worked - a miserable run - not a single success from what I can see. Almost car crash disasters. And then BT. What's he doing? How and why was he appointed? Shifty, grifting no-mark. He should be unemployed. And possibly criminally investigated.
