Peter Hennessy's The Secret State: Preparing for the Worst 1945-2010 is the story of secret government plans for combatting attacks on Britain, from the Cold War to modern counter-terrorism.

Now completely revised and updated, Peter Hennessy's acclaimed account of the secret state includes material from a host of recently declassified documents, to give an up-to-date picture of Whitehall's efforts to defend the safety of the realm.

What were the secret plans for Britain if World War Three had erupted and 'breakdown' had occurred? When would the Queen have been informed and where would she have gone? How does the contingency planning for a national emergency work today? By what procedures would the Prime Minister authorise a nuclear strike and how would those orders be carried out? This book now gives the most detailed and authoritative answers to all these questions.

'Riveting, path-breaking and wonderfully readable'
  Christopher Andrew, The Times

'Effective and vivid ... One of the fascinations of this book is the bureaucratic aridity to which Whitehall reduced concepts of bloodcurdling awfulness'
  Philip Ziegler, Daily Telegraph

'An insider's insider, if ever there was one'
  Anthony Howard, New Statesman

'One of those rare books that reflects credit not only on the author but on its subjects too'
  John Crace, Guardian
