"As a result we have pulled together a number of contracts into one (covering issues like phone line providers, mobile phones, internet providers and school systems) rather than having a number of separate ones. This is currently out to tender."

The spokesperson added: "ECC has put together the tender but has set up a framework to allow other public sector providers across the county to also come in and use the contract for their own services (including CCTV networks)."

The list of bodies that may benefit from the NGN include Essex and Norfolk County Council, NHS bodies, unitary, district, borough and parish councils, fire and rescue authorities, police authorities, educational establishments and voluntary sector charities.

"We are taking the initiative to upgrade out network in order to be able to work more flexibly and more closely with partners," said councillor Peter Martin, leader of Essex County Council.

"The call has gone out to organisations that may be able to provide the service that we require and a decision will be made later in year."
