It has been specualted that should MAG bid for Stansted they will sell 50% of the group to an outside investor. It has been said one interested parties is the investment arm of the Abu Dhabi government and it was then suggested if they were succesful EY would set up a Manchester base. One could there speculate in order to operate this they may see a shareholding in Aer Lingus (an EU based airline) has benefits?
Probably totally pie in the sky but who knows.
