Back in the real world
I wonder exactly how much more effective a separated Openreach would be in rolling out FTTC in rural areas without BT's financial resources behind it. And as for the companies listed as offering FTTP it wasn't clear just what areas AQL & Gigaclear are operating in whilst Hyperoptic does show a map of S England the areas where it's registering interest seem considerably greater than those where it's actually taking orders.
I doubt that separating Openreach or bringing more companies into the field would help Chris Bryant's constituents. What's more likely is to find them all fighting like rats over the 10% most profitable areas.
