I was having a goo chat with someone high up in the Plc a week or so ago. the 1bn over 10 years has been revised and cut to around 750m due to the chines investor's getting a bit jittery. plus the building work has been scaled back and will not be as vast as previously reported.
plus the price quoted for materials i.e concrete has increased in value as there was put in pre brexit and the crash of sterling quote.. that's why the start of the building work has been put back till at least may 2017
