Olympics

I've been determined to investigate 2012's efforts to stop people talking about the details of the Olympic project since I was told last year that new staff at London 2012 were required to sign confidentiality agreements.

I wondered why a project with so much public money going into it - £9.3bn - needed to be so secretive.

Now I have learned that companies building the facilities in east London are being forced to sign draconian gagging orders to keep quiet about the details of the project.
