I consider that the hon. Member for Cambridge University (Mr. Pickthorn) has got hold of the wrong end of the stick. I do not consider that the question of whether an hon. Member should remain a Member of this House on receiving an appointment is a question to be decided by the Prime Minister. It seems to me that it is entirely a matter for the electorate to say whether a Member should remain a Member of this House. The fact that a man is a Member of this House should have nothing whatever to do with the consideration of the qualifications of a Member for a post. It is looking at the question from the wrong end of the telescope to say that the holding of a post should be a disqualification for a Member of this House on the grounds that the Member is or is not of use.
