I have three reasonably well established Giant Viper Bugloss – echium pinnana They have all developed black blemishes, with a white outer, on their leaves All three are in large tubs and potted with a generic soil, mixed with some sharp sand Can anyone advise on this?

This appears bacterial! I would apply the fungicide of your choice, and be sure that the soil has a chance to dry out down to about halfway into the pot between waterings.

For now, do not cut the infected leaves. Since it does not have many, I would only cut them once they die, completely.
