Will my hon. Friend take note of the warnings issued by members of the Metropolitan bench to the effect that the £5 note in its present form is a dangerous instrument and, in certain lights, can be very readily confused with the £1 note, as has been the experience of many members of the population, including my noble Friend the Member for Aberdeen, South (Lady Tweedsmuir), who handed a £1 note over the counter the other day and received £4 10s. in change? In those circumstances, would it not be for the protection of the Revenue, apart from anything else, to look into this matter more closely than my hon. Friend is prepared to do?
