If we create a Greater South East body, exactly how far would it

One thing that's puzzled me. Why was the NSE boundary set the way it was?
So we have all of BR(SR), fine, which I suppose drags in Exeter though
that's a bit of a strange inclusion. We have IC lines up to just before the
first(ish) major station (Leamington, Northampton, Huntingdon) so you can't
get an IC train to get there. But why King's Lynn and not Norwich (DMU vs
IC?), and what about the rest of East Anglia? Why so little of BR(WR)?
