Any objections?
I would normally expect, in the tradition of winning spectrum auctions via M'Learned colleagues, for the networks not involved in this decision (i.e. the other two: EE and Vodafone) to lawyer up against this decision.
I can't see EE wanting to upset their new BT Overlords who'll want to avoid rocking any OFCOM boats until 1. The EE acquisition is rubber stamped + ink is dry and 2. the investigation into OpenReach is over.
So that would leave Vodafone to challenge it alone, and I can't see them fighting a solo battle on that front.
