SOUTHAMPTON map-maker Ordnance Survey could face privatisation as part of the Government’s spending review proposals.

Plans to “develop options to bring private capital into the OS before 2020” were revealed as part of today’s Government announcements.

And plans to explore the sale of the Government’s 49 per cent stake in Whiteley-based National Air Traffic Services (NATS) were also revealed.

They form part of Government plans to sell off up to £5billion of “corporate and financial assets” by March 2020.

Responding to the news, a spokesman for OS said: "No decision has been taken at this time. Ordnance Survey became a Government Company in April 2015 and time is needed to allow the organisation to implement its strategy and realise the benefits of the new model. This is a decision to explore options of private capital investment into OS.

"As part of plans to secure the long-term growth of OS, this announcement signals that Government will begin to explore the potential role for private sector capital into the organisation."
