Dr Julian Lewis: Is it an example of smart procurement to save a derisory sum by removing the planned cannon from the Eurofighter Typhoon, or is it penny-pinching folly?

[Dr Lewis Moonie: That is another piece of iterative behaviour from Conservative Members. We have considered the question of the cannon at great length on many occasions. It is the wish of our Royal Air Force that the cannon should not be fitted to this aircraft because it might cause problems, and we are happy to go along with that.]
