Reported today (20.10.2011):
"Cornwall Council have approved Sainsbury’s planning application at the current heliport site [PZE], subject to conditions on the proportion of food and non-food items they’ll stock."
This is just the first step in the heliport's move from Penzance to St.Erth.
BIH have also submitted a planning application for the St.Erth site which is awaiting an outcome.
