Simon states in this interview some of the conditions attached as part of their investing strategy. They have pretty much tied them up and call the shots.
Rathlin need permission from Reabold to raise funds as per their initial investment agreement. So why would Rebold let someone else lend them money when they can.
I think that now we have the extra money that they are trying to do a deal with Rathlin. Rathlin have not enough money to pay for their 66% share of costs. imo Once Rathlin funds secured then we will get a further update.
