Jon that would be entirely down to the board and an agreement between shareholders. Putting more money in would mean either a cash-call, which means ALL shareholders put more money in to support the business with the % remaining the same OR you put more money in for something in return, typically an increase in shareholding in the business.
My gut says if 49rs put more money in the short term, it will be to buy a majority in the business/ outright, Radz gets his money back and probably wants to stay on as Chairman as part of the deal. They will sensibly only likely do this once we consolidate ourselves in the EPL, a phrase which has been mentioned here and there since May.
I don’t think this will be discussed until March next year if anything is to happen. Who knows.
