Loyalty in an age of whistle-blowing & Wikileaks

Until recently, leaking confidential information was perceived as disloyal and irresponsible and not only was it rare but involved a moral dilemma.  Yet now, it is secrecy, confidentiality and privacy that are stigmatised and Wikileaks is lauded for enabling individuals to spill the beans.  Is this development a triumph for transparency or a blow to moral integrity?  This Battle of Ideas debate is superb and speakers include: Mick Hume, editor-at-large, spiked; Joyce McMillan, theatre critic, Scotsman: Henry Porter, political columnist, Observer; Gwyn Prins, research professor, LSE and Richard Sexton, partner, PwC.
