At bloody last.
Seriously, why has it taken so long to notice this blatant conflict of interest.
There's a reason that we lag behind so many other countries who don't have this problem.
Break them up and then tell OpenReach that they have to supply every house in the country, and charge the same for all lines, to everyone who asks.
Then watch as BT die a death except with granny who wouldn't know who else to use, and has to start competing properly again, and lower their stupendous prices for what they offer.
Then, you might even be able to charge bloke-in-London an extra quid a month over what he'd have paid before to give bloke-in-the-middle-of-nowhere some kind of usable connection for the same price.
