What is happening at Dolphin Quay?

There seems to be a slight air of mystery about the site of Dolphin Quay. In October last year, Havant Borough Council seemed confident that a final legal agreement between the Council and the developer/buyers (Wilson House Ltd) was about to be signed. Until now however,  nine months later, this agreement has not been signed. The Council do not know what the delay is, and have said their legal team have chased the applicant's solicitors several times but are still awaiting a response.
