Don't think there is a set date,but it is when the 'golden share' is transferred if agreeing to the 25p in the pound. Apparently a 35p in the pound deal can also be arranged, but that is over a 3 year period.
Another thing as well for people thinking MA will get it by potentially increasing his bid, why can't those who've already bidded more just leave their offer on the table if they feel the price is getting too high?
We'd start next season on minus 15, why would you bother buying if you are practically consigning the club to another season in League One at best, missing out on millions from being in the Championship?
