It's planned for Euston and, as in this thread and elsewhere, services for the north are reduced.
Some intermediate stops will lose out on TPH to London and won't get such a fast service, but that's not equivalent to denying "The North" of rail services. That's like saying that HS1 is designed to deny Kent of services because it goes to St Pancras and doesn't serve Tonbridge...
