These IPC notes are very illuminating.
Three messages come across clearly:
1 National Grid admit their consultation process to date has been inadequate
2 National Grid are still not answering the key questions posed and as they have done so many times in the past (including to Liam Fox, Tessa Munt and Parliament) are still promising answers
3 The IPC view is that National Grid still need to review their consultation process and take on board the consultation feedback
