Favourites to purchase are the French -- if they get it watch them transfer all the illegals in Calais to Dover then refuse to take them back. All the human rights enthusiasts will then demand we keep them here.
One important issue I'm worried about is if our old 'enemy' the French buy the ports up. I'm neither paranoid nor 'o'phile' but in reality the French are still not too keen on us. Old wounds take a long time to heal.
