I merely want to gain a better understanding of subsection (2)(b). I ask because the briefing notes, so invaluable in Committee, remain remarkably silent about this clause. I am slightly confused, and I am sure that the Minister will explain it with his customary clarity. The provision suggests that if a member of the Associated Society of Locomotive Engineers and Firemen, for example, chooses to train and become a member of the British Transport police, it would be possible, subject to

''the consent of the Chief Constable'',

for him to remain a member of ASLEF, contrary to subsection (1). Have I misunderstood the provisions?
