Nobody purporting to be in the know is saying there's any issues so for me it's going to happen. Cash is probably sat in a solicitors bank account and the trigger will be the PL thumbs up. As soon as that is given the deal can't be stopped as this is the final condition, it is then formally completed and control of the cash then moves from the buyer to seller. Official announcements may take longer due to the lockdown and coordination of the parties but my guess is that as soon as PL give the OK we will hear it is a done deal.
But what do I know?
