Hello Rowland,
Involved in the negotiations for the development of the project Marina de Cope are:
- Consejería de Turismo de Murcia (Regional authority in Murcia for tourist affairs)
- Town Halls of Lorca and Águilas municipalities.
- The majority of the land owners.
- Real Estates and Developers: Valleduero, Avocasa, Extremalia, Iberdrola Inmobiliaria, Actura and Summa.
All of this parts are together in which is called "Consorcio Marina de Cope", created to become the project a reality.
Apparently, Goverment of Spain says will go to Spanish Courts to avoid the creation of this project, but the Regional Goverment of Murcia (PP party) wants to go ahead.
Sorry, that´s all I know about this for the moment. You may find contact details of the promoters and real estate companies mentioned above though the internet.
