Before the hon. Member leaves the question of the desirability of the proposal and comes on to the question of whether it is practicable, would he tell me this? He made the only understandable argument that I could gather from what he said against the desirability, the fact that a man was entitled to keep his political opinions secret. Would he be in favour of this Motion if it exempted from its operation only those who expressly withheld their consent from the publication, and published all the others?
