Re: BT NextGenitalia.
That's a wee bit unfair. This wasn't BT, this was a subsidiary *in another country, with a (presumably) very different and complex regulatory process* who appears to have been cooking the books. I'm guessing it was more a case of inflated numbers and stuff being rapidly shuffled between divisions and/or bank accounts to make things look good and keep bonuses high.
I've no doubt that people will be running around within BT doing damage limitation, but this situation is absolutely nothing to do with BT's practices in this country, nor does it have anything to do with the politics of Openreach and Ofcom.
Also, it's worth noting that BT's employees in the UK - including in subsidiary companies - have to undertake a mandatory set of annual training courses which make it clear that equivalence has to be maintained and things like bribery and corruption are completely unacceptable. Which may not stop people, but at least they can't claim that they haven't been explicitly warned.
You have to wonder if other large-scale companies follow the same best-practice. Such as Tesco, with their £326m accounting scandal...
[ObDisclaimer: I worked for BT, about a decade ago. I don't have any shares in them, though, which may not be a bad thing at present!]
