Rob stuffed the culvert and his fertility figures were way down so that Charlie examined them because low fertility meant the profit margin was cut to the bone. Rob also took excessive amounts of time off and his staff were frightened of him. He was manager when contaminated material got into the silage.
Charlie managed an already barely profitable business during a botulism outbreak and clearly related very well to the staff and animals.
Justin doesn't like bad press but it's Charlie's professional reputation that's on the line.
I'm wondering if Charlie might fight back, if Stefan is living locally and has read the paper, if the Berrow staff might take their redundancy money and speak up for C.
Most of all I wonder if David and Jennifer might get over their amnesia and if Adam will risk his relationship with Ian to defend Charlie's reputation.
At the very least, an article in the Echo should get the villagers talking about Rob and putting two and two together.
