Could Burwill's "right of first refusal" be contributing to the delays?
Since TH at pre-open on 21/12, we have missed 8 trading days. This will become 13 days if the full suspension extension is used. Hopefully we won't need that much time.
If the current negotiations were just 2 parties (A40 and Burwill), it should have been plenty of time already, given past dealings with Burwill were concluded swiftly during TH.
Therefore, my thoughts are there are at least 3 parties involved.
I think the most likely (and positive) outcome is a similar update as AJM recently announced last month.
