From the Telegraph:
If charged, the officer will appear at the Old Bailey in London, which hears all such Official Secrets cases. He faces a maximum sentence of 14 years if convicted. Lt Col McNally joined the Army as a private in 1977 and worked his way up through the ranks before being commissioned as an officer in 1995. He is thought to be one of the Army's most senior former non-commissioned officers.I think this could turn out to be another bloody fiasco.
A senior officer told the Sun of Lt Col McNally's case: "This is deeply embarrassing for the British Army and completely unprecedented. In mitigation, there is no suggestion that any of the figures were being leaked to the Taliban."
