The go-to intelligence expert and author of MI6 has “provided the clearest review of GCHQ and its predecessors in a publicly available book” (Firetrench). Signal intelligence is the most secret, and most misunderstood, weapon in the modern espionage arsenal. As a reliable source of information, it is unequalled, which is why Government Communications Headquarters, almost universally known as GCHQ, is several times larger than the two smaller, but more familiar, organizations, MI5 and MI6. Because of its extreme sensitivity, and the ease with which its methods can be compromised, GCHQ’s activities remain cloaked in secrecy. In GCHQ: The Secret Wireless War 1900-1986, the renowned expert Nigel West traces GCHQ’s origins back to the early days of wireless and gives a detailed account of its development since that time. From the moment that Marconi succeeded in transmitting a radio signal across the Channel, Britain has been engaged in a secret wireless war, first against the Kaiser, then Hitler and the Soviet Union. Following painstaking research, Nigel West is able to describe all GCHQ’s disciplines, including direction-finding, interception and traffic analysis, and code-breaking. Also explained is the work of several lesser known units such as the wartime Special Wireless Groups and the top-secret Radio Security Service. Laced with some truly remarkable anecdotes, this edition of this important book will intrigue historians, intelligence professionals and general readers alike. “Nigel West is an acknowledged expert in this field of literature and his latest book is fascinating and intriguing.” —Books Monthly “Rich in the kind of detail from which all students of radio and military history can learn.” —The Spectrum Monitor

This report details the work of the Intelligence and Security Committee (ISC) for the period December 2008 to July 2009. The majority of the Committee's time during the reporting period was spent examining and taking evidence on the policy, administration and expenditure of the three intelligence and security Agencies and the wider intelligence community. The remainder of the Committee's time this year has been spent on two separate investigations: updating its "Review of the Intelligence on the London Terrorist Attacks on 7 July 2005" to reflect developments since the review was originally sent to the Prime Minister on 8 July 2008 (the completed review was published on 19 May 2009, Cm. 7617, ISBN 9780101761727); and conducting an investigation - as a result of allegations surrounding the case of Binyam Mohamed al-Habashi - into the policies and procedures that the Agencies follow with regard to contact with detainees, and also intelligence sharing more widely.

This text describes how the government has been concealing the evidence of routine penetration of British airspace by rationally controlled machines from outside Earth, over which the military infrastructure has little or no control. It suggests that there is evidence that there has been an official shift in policy, and that there is a desire to disseminate to the public top secret UFO data collected over the past 50 years. Having examined the available evidence, the author is convinced that there is an active alien presence on the Earth, and that official confirmation of such a presence will soon be forthcoming.
