President Obama’s National Security Adviser General James Jones says Americans will be shocked by the findings of a White House inquiry into the intelligence failures leading up to the attempted Christmas Day airliner bombing. From Washington, here is Mark Mardell.

President Obama’s top security adviser, General James Jones, says that the president is very concerned that America’s intelligence agencies failed to make use the information they had to stop the Detroit bomb plotter boarding a plane bound for the States and failed to join the dots over Fort Hood. Major Nidal Hasan has been charged with shooting dead 13 fellow soldiers in that incident. The president’s national security adviser added, "It’s not theatre. He's alarmed". The president’s due to speak soon about this and make public the results of an investigation into what went wrong with the Detroit case. A report stripped to sensitive material will be published, and General Jones says people will be worried by what they read.
