Identity Cards Bill

As the mover of the amendment has said, we had a long and at times amusing debate on this on the previous occasion that we discussed the Bill in Committee. The only point on which I would be grateful to receive an answer is this: if you are someone with several names, all lawfully used, will you be able to choose which is to be the principal name, so to speak; that is, that recorded under paragraph 1(a) rather than paragraph 1(b)?
