I have to declare an interest here, as I am a BT pensioner, after 24 years as an Engineer.
What Hodge is saying here seems to be true...BT do have a monopoly.
But that monopoly comes from having many years where they and the predecessor, the GPO, installed every telephone line and cable in the country.
I have recently upgraded my BT connection to Infinity and now get about 36 mega pixies, which I am very pleased with. But if anybody can get to the bottom of whether BT is abusing its monopoly, it will be Hodge and her committee. She is a positive rottweiler !
