Dr Julian Lewis: May we have a statement from the Secretary of State for Defence on what has been dubbed "Operation Homework", in which the Ministry of Defence supplied information to one Master Euan Blair on the arguments in favour of the nuclear deterrent? If the Secretary of State has more important things to do, may Conservative Members, in the spirit of Christmas, offer free tuition to Euan on the merits of nuclear deterrence? We would be quite happy to teach him about that subject now, just as we had to teach his father about it 15 or 20 years ago.
